I shoot all my bows with a pretty long hold at anchor, maybe 1-3seconds typically. I haven't really noticed that doing anything terrible.
I also commonly leave a bow drawn on the tree for long enough to quickly step back and look, then mark the belly side with a pencil where I need to scrape. Maybe 10 seconds.
I try to reduce how much I need to do that, but at the end of the day a well tillered bow will last longer, and you got to do what you got to do to make a well tillered bow.
