RE: issue not sure about
You can't just "have" your bow tuned, if you mean you took it to a shop and paid them to do it. Your grip is probably different from that of the guy who did it and that can make a big difference in how the bow shoots. So, unless you did the shooting and they did the adjustments, the best they did was get it close. It's up to you to do the fine tuning to make it right. Other than wanting to make that point, I agree with BGfisher.
