With PreScreen Videos under way now, there are plenty of opportunities to redo videos that have a flaw in them. Maybe you end up with lots of videos with different flaws in them. Shouldn't you theoretically be able to redo them until you get one just right? Or, maybe at some point, you just say "this one is good enough". Where is the threshold between not trying hard enough to get it right and just saying "well, there you go, this is my playing level, hope you like it."
