i have a 5 pin sight so what yards do i need to set them at

I've got mine set at 20-30-40-50-60.

i'll try to but, i dont wont to have to take it back to the bow shop, and say i mesed it up will you fix it again.

i played with my sight's and got it to shoot strait and can hit the bullseye with the top pen at about 15 yard's, so tomorow i'll try to sight the other pen's in.

OK i thank i pretty much got it sighted in, but I'm only using the top two pens, don't thank I'm going to be shooting much farther than that.

is there any other tuning i need to do?
the resin i ask is my arrows seem to hit the target tilted up or downsometimes and sometimes tilted to the left or right, but only at longer distances.

please help me, i wont to learn how to set up my bow.
