An interesting observation I've noticed lately. After setting up my shadowcat I started using it bare fingers as I am a barebow shooter anyway and my tab was brand new and not 'shot in' I tuned it to fingers but eventually decided to break in the new tab. Using it, all arrows went to the left. at about 20 yards they were about 4'' - 6'' left of center.I realised the thickness of the tab was in effect moving my anchor point at the side of the mouth out slightly and consequently the point to the left. Doesn't need much to make a big difference.Probably means nothing these days as almost everybody shoots sights and release aid.
