Yeah, that's really what pros look for, that's why they break a lane down. Either they're trying to create "miss" room, or look for more area, not because they need it to mask their inaccuracies, but when you feel like you have all the room in the world whether you do or not, you loosen up, your armswing gets free, and you are able to execute better. You DO want to look for the zone on the lane with the most area you can find, because that's just smart bowling. The point is to use whatever tools you have to knock the pins down, and if you're a master at reading ball reaction and at laneplay, you're going to be beating a lot of guys who might physically throw it better than you.
Splitting boards is only one small facet to accuracy and ball motion. The pins KNOW if you're tight, and so does the lane. You can technically split the same board on two consecutive shots and get two different results if you throw one ball tight and one with confidence. Sometimes that's all I've adjusted this year, because I've felt myself creeping back into trying to control everything. 4 pin here, mixer 7, ring 10, all on target and hitting the pocket, then I realize I'm tightening up and tell myself just to throw the damn ball, and all the sudden it's back to strikes when I hadn't moved or adjusted anything.
Again, accuracy and the techy stuff is very important, but you pay attention to that for the purpose of knocking the pins down . . so eventually you need to tie it all together. Took me WAY too long to realize that, and that's even with several people on here trying to beat it into my head.
