Shooter speed calculation from vision tracking

[Alon]

Hi,
I was wondering how other teams who used a shooter this year calculated its
speed with vision tracking.
In our team, we built a table for speed-distance, plug it into excel and used polynomial regression to give us a function that transfers a given distance from the high goal to the desired shooter speed needed to score. with this method we managed to hit the goal from almost any given point on the field.

The disadvantages of this method,i think, are that
1) it can maybe be not precise if you have not done your measurement right, 2) it is a little time consuming and need to be redone after every slight change in the shooter mechanism.

My question is, how did your team calculate your flywheel/angle/shooter speed from a given distance?

i know some teams did it with physical calculation but i have always thought that air drag / ball spin (magnus effect) are really hard to predict and calculate. maybe someone did it that way and can explain how? or maybe someone did it with a different approach and can share their experience?

if you have any external resources / reading material on the subject please share them

thanks for you answers!
