Many people do find that, at the start of practice or a game, they will not be at their prime. We have to get adjusted to the lane conditions, sort of get into the groove of things, and then start bowling. To me, it normally does take a few balls to figure out my timing, some mechanical things, and where I have to play my line(s). Yet I do not see many people having to figure out their timing and mechanics right before/during a game. I suppose that's just a me-thing, sort of like how you have to look for where your release is.
What some of you having to move laterally may be is the oil transitioning down the lanes. I know for a fact that everyone has to end up moving over a bit to make up for the oil transition. And normally, people will have a decent first game, and their second and third games are normally their strongest. Anything past that, and you will start to tire. So, it is normal for you to progressively get better as you go further into games.
And as I said above, we all have a little tweaking we have to do every time we go to bowl on a different day. Some people have to watch their timing (me). Some, like you, need to watch their release. Other may have to look at how big of a first step they have, how large their slide is, etc. So, I think it's completely normal for you to have something that you have to change and work on everyday you go to bowl. I know I don't have to worry about my release point, but we all have different things we need to look at and watch over.
I'm not a pro or anything, I'm 15. But from watching more experienced people bowl, this is what I think happens to a lot of people.
