Here are the definitions/causes I have (got 'em out of the Ritger advanced program).
solid ring 10 - the ball has too much energy when it hits the pins. use a stronger ball that will use up energy faster.
Sometimes I will move my feet a board left instead.

Weak 10 - Ball rolling out, using too much energy getting to the pins. Try weaker or shinier ball. If I really think it's the right ball, but carrydown or something is getting in the way, I'll move my feet a board right.

One advantage of bowling over golf
is that you seldom lose the ball.

I took this from an earlier thread.

There is one reason you leave a 10 pin. It's because the ball is deflecting/not driving through the pocket. There are 2 reasons for that with multiple sub reasons.

1. Ball is sliding.
..a. Too much speed
..b. Ball is tugged and stays in the oil too long.
..c. Turned/spin/topped the ball too much, so it pick's up it's roll to late.
..d. Hung up in the thumb.
..e. Lofted the ball too far on the lane.
..f. Not enough lift/leverage at the release.

2. Ball is rolled out/dead at the pocket.
..a. Ball speed too slow.
..b. Swung the ball too far/crossed too many boards.
..c. Not enough side turn.
..d. Not enough loft when the heads hook.

This doesn't take into account of not matchiing up with the proper ball and layout. Either of which can be thrown into one of the 2 catagories above. This should explain it for the most part. =:^D

I agree with everyone except I was taught to move forward (flat) or backward (ringing) 4-8 inches to correct for 10 pins. Seemed really odd to me until I tried it and it works better than lateral moment for me.
