So I finally mostly figured out how the number work. Refer yourself to the byte strings listed below by jstout.
ex 06 pc @2be14 f7 34 80 80
The first byte is the chance the pass is on target. It gets compared to a random byte from 00-FF. If its less than the random byte its on target otherwise there is a chance for an underthrow/overthrow
06PC= 4% chance of no underthrow/overthrow
100PC= 56% chance of being no underthrow/overthrow
Underthrow= ball goes out of bounds, stopped wr has to move to get the ball, Wr stops mid route.
Overthrow= ball potentially sails way over WR head, just enough that he can jump an catch it or dive and catch it
The second byte determines if the pass will be an underthrow or overthrow if its not ON target. If the byte is greater than the random number it will be under thrown
A 06PC will have a 20% chance of underthrowing it if the ball is off target...or a total chance of 19.6% of throwing an underthrow on any pass
A 100PC qb will have a 9% chance of underthrowing it if the ball is off target...or a total chance of 4% of throwing an underthrow on any pass.
A 06PC will have a 76.9% chance of throwing an overthrow on any pass
A 100PC qb will have a 40% chance of throwing an overthrow on any pass.
The 3rd byte has something to do with the underthrows. I'm not quite sure what it does. Perhaps the smaller the number the more catchable the underthrows tend to be.There was too much code to sort through for me to try and figure it out.
The 4th byte has to do with overthrows. And this is kind of interesting. The bytes only range from 68-80. However if you set this byte to 0. The overthrows are never overthrows. They act like normal on target passes. So by lowering this byte you could drastically reduce the number of long jj bombs or at least moreso for shitty qbs. Or you could increase the chance for underthrows. Timed jj's would still work as normal.
It's funny because after looking at this the 50-56 pc qb is probably the best for jjs since they run little risk of getting jj inted except by carrier/haddix and they will get more lob balls than a higer pc qb.
Some additional info if anyone wants to goof around with values. Each Accuracy is 4 hex numbers each is pulled and compared to a different random number depending on the situation.
