I was bowling in a tournament today, and I had a bit of a problem on one shot. The ball stuck on my hand, so I just stopped myself on the approach. Unfortunately, I slid just a little over the foul line. However, it didn't count me a foul and the rest of the people on my lanes just told me to keep going and not worry about it. I was told that because it was not a "full delivery", it didn't matter. I have been worrying about it all day though...
Is this correct according to the rulebook? Any info is appreciated!
