A. pretty sure we weren't talking about you but apparently you need to make it about you
B. if he has slow or lower ball speed and not carrying I would pretty well bet that if he picked his speed up, thus getting the ball farther down the lane. If the ball didn't 'hit' at this point the player could then move right (assuming the bowler is right handed)
I am using extreme logic

So if I'm hitting the pocket and leaving plaque or flat 10 pins, I should just throw it slower? With your logic, if I do that it should work, correct? Why should anybody change balls when  they have a bad reaction if ball speed would just make a bigger difference? Does it work the other way? How come when Chris Barnes keeps going through the face, he switches balls instead of just throwing it faster?

This is not about you?
And we are talking about a casual bowler, competing on a typical house condition NOT Chris Barnes on tour....YOU obviously want to either argue or dispute anything or everything I've posted...
It is quite simple actually if a ball is traveling too slow, NOT an average speed matching the rev rate slow, but too slow of a ball speed for rev rate, the bowling ball is obviously losing energy...now there are 2 forms of losing energy, a bowling ball skidding in oil trying to change direction and thus losing energy in the process or a bowling ball traveling too slow losing its rotational integrity thus not hitting, meaning it needs to maintain its rotational integrity longer which generally translates to less surface or more speed...
I do not know how to explain it any better than that
