Your puny EF scale is no match to the CF scale (upgraded damage indicators coming soon)

Copy and pasted from the old post (with minor changes):

Keep in mind this is probably not accurate. Although I tried to be as accurate as I could, strength estimations may be wildly off.

Upgraded my survey for the Elie F5. I was unable to get any higher quality imagery north of the highway and south of town, so I have decided to not have anything above F0 in those areas.

Contours are using more detailed strength classes.

Contours

• Cyan: F0 - 65 MPH
• Green: F1 - 86 MPH
• Dark Green: F1 Strong - 103 MPH
• Yellow: F2 - 111 MPH
• Orange: F3 - 136 MPH
• Red-Orange: F3 Strong - 150 MPH
• Red: F4 - 166 MPH
• Dark Red: F4 Strong - 184 MPH
• Pink: F4+ - 192 MPH
• Purple: F5 "Weak" - 200 MPH
• Blue: F5 Mid - 208 MPH
• White: F5 Strong - 225 MPH
• Black: "F6" - 235 MPH (Possible)
• Light Blue: Possible Damage
• Grey: Unknown

(Colour scheme is modified from joshoctober16's, although windspeeds have been lowered for some of the higher ones)

Windspeeds based on modern EF scale and Derived EF scale, where EF5 ended at 234 MPH. Grey Unknown contour is there as tornado was likely intense to violent in that area but I could not find any damage to support it. Light Blue Possible Damage contour was added as the tornado may have continued past the lifting of the visible condensation funnel, the one north is seen as a mark in the field, possibly the reformation of the tornado as a second funnel was seen attempting to reach the ground after the Elie tornado had lifted.

what rule could this have possibly broken

Currently making this survey, although I have very little to go off and much of this path is simply a placeholder, would like any possible images from the fields north of the mill (if any exist) for a better path centreline. if nobody has anything, that's alright since I could barely find anything myself, just hoping.
