I wanna make up a theory
(The ss is from the last scene)
I read at somewhere that walter always told the tempature wrong to the people he teached so they got never reached to walt's level. That was walter's secret ingrident i guess
But for the theory, i wanna assume that here it says PRESSURE GAUGE because Jack and his crew didnt actually cared about the equipments so they just put a random gauge hand to be used as tempature gauge hand, considering how jack really doesnt care about professionalty (for example "we can paint it blue with food coloring" scene) it can be possible that they just used a random gauge hand.
But we can see tempature isnt actually 85 like how walt told to Gale at earlier seasons, it looks like a little above of 85 maybe 86?
We also know that skinny pete says that "the products is bomb than it has ever been"
So my theory is, Jesse found a better tempature to cook, which maybe Walt already knew but he always used the 85 temp when he is nearby people but when he was alone, the secret ingrident tempature 86 kicks in. And he peaks at %99,1 from a product that he made in a rv lab which sucks for a meth lab.
And maybe Jesse broke this record of Heisenberg with 86 tempature because his equipments was slightly better. At least it was a real lab, so purity climbed up to %99,5? Or more idk
Obviously this theory has its own flaws
First one is: we are believing to a meth taste of a methhead (skinny pete)
And the second bigger flaw is: I dont know why jesse would even try to find the perfect tempature?
I mean they had to put some scenes of jesse being punished if he made bad, and maybe gets a prize like ice cream when he makes a better product so it would make sense for jesse to find the 86 tempature. Or even care to use it again, he wouldnt give a fuck about the difference
