Technically you will loose some force the longer the ball is in the roll phase because after the ball enters the roll phase it starts to loose rev rate. But if that amount of rev rate lost is enough to create any actual perceived difference in carry beyond the lower entry angle is the question...Mo Pinel may have insight on that.MegaMav wrote:
I dont concern myself with the ball rolling for too long. If the ball rolls excessively early you will lose entry angle, not force.
If the lane is flat, the ball slows down from air resistance and friction, which isnt much in the roll phase.
As you can imagine it takes a long time for something heavy with momentum to slow down and reduce force.
Once a ball is rolling without rotation the ball is no longer slipping.
I am not aware of any formal study on this, but it would be measured with CATS.
Seeing good entry angle, position in the pocket and roll phase is good enough for me.
Where longer roll phase does matter though is with people that have low tilt...which I believe TheJesus does have low tilt. The lower your tilt is the shorter your roll phase is before the ball rolls out as most of us know.
Carry is all physics as was discussed earlier...but one thing that hasn't been mentioned is the fact that a large part of it is the gyroscopic force the ball is creating. The higher that is the less deflection you will see which equals better carry. Part of what increases the gyroscopic force is increased rev rate and also stronger PSA's. So the earlier the ball hits the pins while in the hook phase the weaker the gyroscopic force is as it gets stronger as the balls rev rate increases and as the ball gets closer to it's preferred spin axis.
I also don't know of any published tests like what you are looking for...but if you can get in touch with Mo Pinel I'm sure he's seen some info on that and may be able to/willing to help.
