Even "wasting" ammo, the average to be considered "average" is around 5% hit rate. I spray with the best of them, and I'm around 6%. Depending on the planes I fly, I go up to 8-10%.
1% is absolutely abyssmally bad, no 2 ways about it.
P.S. have you tried no tracers in a serious attempt? Fly without them for 2-3 months of steady fighting. Your hit % will probably jump up to 3x what it is now.
