If the string & cables are the right length and have enough twists to them, then there won't be a noticable affect onaccruacy.

However, some string materials creep significantly in the first few hundred shots. Creep is when the string stretches and doesn't return to it's original length.

From your discription, your strings and cables have creeped enough to throw your bow out of tune. Re-tuning your bow should get you back to where you were if string creep is the problem.It's just a matter of a few twists on the strings and cables, then re-tune to the new specifications.

Be sure to measure everything - ATA, brace height, etc so you can check in the future to seeif anything changes. If you know exactly what changed, it's a lot easier todiagnose & fix it.

Hope this helps,
