Hoe interpreteert men CBR slagings statistieken?

Ik ben dus op zoek naar een rijschool en kijk via het CBR naar slagingspercentages. Maar ik snap er niet zo veel van... Ik heb een voorbeeld:

https://preview.redd.it/lm3ue5gjs6kh1.png?width=978&format=png&auto=webp&s=4729755e2f31bfd9477ab07f5ff78731cee1ad70

Het gaat om vier statistieken. Allereerst het slagingspercentage rijschool. Betekend dit dat 71% van degene die lessen bij deze rijschool hun examen halen? Is die 29% (nog) niet geslaagd, zijn die ermee gestopt of zijn die geswitched...?

Dan heb je het slagingspercentage eerste examens. 100% en 5. Betekend dat dat deze rijschool maar 5 mensen heeft begeleid met hun eerste rijexamen en dat die allemaal geslaagd zijn?

Dan heb je het slagingspercentage (aantal herexamens). Wat hier op 58% en 12 staat. Zijn dit dan 12 mensen die hier geslaagd zijn, na geswitched te zijn van rijschool? Want het slagingspercentage bij eerste examens is 100%...

Dan heb je gemiddelde slagingspercentage examenlocatie. Dat is gewoon het percentage slaging in verhouding met het totale aantal examens in Amsterdam. Klopt dat?

Ik snap voornamelijk de eerste en tweede niet, want die lijken enigszins met elkaar in strijd te zijn?

Thanks!

After/before - trying to give this photo a nostalgic, frozen in time kind of feeling - but I feel I'm always super conservative with postprocessing.

No longer the dumbest person alive - attempt 2 on the Sharpal 202H

I had another go at using the Sharpal 202H, this time with a cheaper Western style chefs knife (angle of 15 degrees or so)

I started at 325, really trying to get to the apex and feeling for a burr. I tend to feel for it by getting my nail caught, but I think I'm getting better at detecting it with bare skin also. I'm gonna buy a tiny pocket microscope just to confirm that what I'm feeling is what I'm looking for - to confirm my intuition.

I then did another pass on 325 on the other side, then switched to 600 on the other side to form a lighter butt, then did another pass on 600 on the other side, then 1000 both sides till the burr wasn't huge, but still there. Then I stropped both sides with a light bit of pressure until I could no longer feel a burr.

The knife goes very cleanly through paper. It goes through a tomato sideways but the tomato does want to start moving about halfway through. It's shaving sharp (now I've got a bald patch on my left arm). Did not try hair whittling, that's not really what I'm going for anyway.

Here's a picture of the edge! It looks very clean, I think. I'm also a bit unsure still how to clamp. it says to leave half an inch from blade edge to the clamp. But the knife is not straight like a caidao - so how do I do that on both clamps? As such I just clamped it as 'straight' as possible (following the spine of the knife) and leaving half an inch on one side and a bit less on the other clamp.

Did I do things right this time?

Sharpening on a Sharpal 202H system - feeling like the dumbest person alive

So, I thought I followed all the instructions properly. But it seems I didn't get to a super sharp level yet and looking closer, the knife's got a bit of a ridge at the start of the edge and there seem to be a few chips also.

When I used the 3000 grit whetstone, there was a bit of flaking off the stone. I definitely kept it wet enough. This implies something with the angle is wrong, but the sharpie test seemed to indicate everything was fine. Sharpened on setting A at about 13 degrees.

I find it quite difficult to feel for a burr also. How long should it take to form? And then when I flip it over on the same grit, should I sharpen until there's a new burr on the other side, or lightly sharpen to get rid of the burr and move to a higher grit?

Edit: The knife isss decently sharp now, getting through paper with ease and also workin quite well for the foodprep i did this morning.

Hoe heb jij je voorbereid op je rijexamen/rijlessen?

Ik heb besloten eindelijk te gaan voor mijn A & B rijbewijzen - met als grootste reden dat ik in het buitenland (gedeeltelijk) met motor of auto wil reizen. (Het liefst had ik mijn rijbewijs in het buitenland voor een prikkie gehaald, maar dat blijkt veel moeilijker dan gedacht)

Als menig ander Nederlander wil ik graag zo weinig mogelijk geld kwijt zijn voor een zo goed mogelijk resultaat.

Hiervoor heb ik dus tweedehands een stuur, pedalenset en schakelpook gekocht om na het oefenen in menige apps (BeamNG, EuroTruck Simulator, Assetto Corsa) weer door te verkopen. Misschien scheelt dat toch iets in de praktijk. Zoniet is het toch leuk om geprobeerd te hebben. VR headset en goede PC heb ik al.

Voor de verkeersregels en borden gebruik ik een aantal Anki decks en kijk ik YouTube videos.

Wat heeft jou nou eigenlijk (enorm) geholpen? En mag je oefenen met familie, buiten lessen om?

En hoe kies je in godsnaam een rijschool? Ik vind dat misschien nog 't moeilijkste deel.

Hartjesdag - (what) are you coming (as)?

Hi!! Only 3 weeks left until Hartjesdag. If you don't know, Hartjesdag is an old Haarlem/Amsterdam tradition. (It's on the third Monday of August, this year that's the 17th)

It is alleged it started as a day where normal people were allowed to hunt deer - 'hertjesdag'. Another historian claims it was originally a festival in celebration of the Germanic goddess of earth (Hertha). After a ban in 1943 under the Nazi occupation, the holiday faded but in 1997 it was reinstated as a hyper-local event - only really being celebrated on one street, the Zeedijk.

Crossdressing seems to have always been a part of the celebration, but since its reinstatement it seems like the main focus.

So! Are you coming?

If you are, what are you planning to dress as? What did you do previous years? Or have you never heard of it whatsoever?

A little request for help!!

So I'm planning to show up as a North-Western Indian bride. I've previously done 'cultural' crossdressing to great success, in Jiangxi, China. Here's a photo! https://i.imgur.com/vskjqfJ.jpeg

I was wondering if anyone would be willing to or knows anyone who would be willing to help me with make-up and a hair-do cause I am terrible at that still.

Bonus points if you can help me find a good lehenga choli! I'm still scouring vinted/marktplaats for the moment....

Looking to try cooking Senegalese - please link recipes you like and gimme tips!

hi!! At the end of 2025 I tried Senegalese food in Paris at a resto called 'Thieb House'. The dish with white rice is Chicken Yassa and the other dish is Lamb Thiebou according to the menu. I fell in love with both so I really wanna try making them! But recipes are scarce and I have no idea how accurate they are.

So please! Send me some recipes you like for either of these dishes or anything else you like.

I did find this one for yassa but idk if it's accurate at all: https://www.americastestkitchen.com/recipes/16064-chicken-yassa-senegalese-braised-chicken-with-caramelized-onion-and-lemon

(I love cooking cuisines from all over the world and so far I've mostly made Asian and Middle Eastern dishes, if you are curious about any i can send them to ya!!)

Roeien of kayakken rond de randstad - wat zijn goede of goedkope plekken?

Ik wil graag roeien met een vriendin, maar in Amsterdam lijkt 't dat het vooral via verenigingen gaat - terwijl we maar eenmalig willen gaan.

Waar kun je goed, voordelig roeien zonder een lidmaatschap te nemen? Kayaken kan evt ook, maar ik heb toch liever roeien.

Stroom door (iets te nauw) gat in de muur - kan dat met IEC kabels?

Ik wil graag een verlengsnoer door een gat in de muur leiden. Het gat is net niet groot genoeg voor een schuko, male of female.

Wat ik overwoog is een schuko male naar IEC 13 (female), die door de muur steken en dan aan de andere kant verbinden met een IEC 14 (male) naar schuko female waar dan vervolgens mijn stekkerdoos in steekt.

Kan dit...? of is dit onverantwoord? Maximale stroomverbruik van de stekkerdoos die hierin moet is nog geen 700w.

Is this scratch a 'beginning mark' or damage caused by the advancing claw?

My friend seems to believe that even after advancing the film is rewinding itself and showing this 'beginning scratch'

She sent a full cartridge in for developing and the lab sent it back because it was not yet exposed according to them, because they could see this 'beginning scratch'

Is this really present on all rolls of film? Is it possible the camera is doing this at all? It seems really unlikely for the cartridge to rewind itself, considering it generally only wants to move one way

So my friend is trying to use a Canon Auto Zoom 518 SV Super 8 for her new short film project. However, the first roll of Vision 3 500T she sent in got sent back, the lab saying the start mark was still visible and the film had not at all advanced. So we put a roll in and yes, it seemed like the roll was not advancing, even thought when fired empty, everything seemed to work fine.

I then tested rotating the advance wheel in the film by hand and it took a good few turns before I felt tension and the film started advancing.

I tested it a few times in camera, marking the spot we left off and sometimes it worked, sometimes it didn't. Sometimes the film bulged a bit, sometimes it didn't.

What's likely going on here? I heard there are QC issues with the films, and the camera seems fine... But it's really hard to say.
