When trying to shoot for acurracy, I wouldn't suggest thinking about much other thenfocusing on thetarget and keeping proper alignment.

Aspects of form need to be worked on until they become something that you do naturally without putting much conscious effect into.

When working on form, I'd suggest onlyworking on one or two aspects at a time. Accuracy shouldn't be one of them.

I very rarely work on breathe control if at all, it was one of those aspects that was picked up rather quickly and something I do automatically.

FWIW, I still work on various aspects of form on about a 50/50 basis with accuracy.
