I don't know why I didn't think of this earlier but better late than never I suppose. Last year I bought my Vectrix new and had it set-up by the proshop. I've since put probably 500 shots on the bow and just now realized that after the break-in period of 100 shots that my string stretched which threw off the tuning and needs to be re-tuned.

For the record, I know very little about and have done zero tuning in my archery career. Despite that, what could I expect to need re-tweaking?
