There's two ways that you could go about doing this, in my eyes. If you know the prize payouts that you want to give, just go ahead and insert them, lock them, and save it as a template so that you don't have to re-enter them every tournament. That way, the $250 gets divvied out, regardless of how many don't show. The other way to do it is as you listed - just bust them out right away. Technically, they have already bought-in with their fee, so they have a seat reserved for them. I would consider it a matter of personal preference, as both should accomplish what you are looking for. Personally, I would have all 20 be bought in, and those that don't show up be busted out w/o having a hitman designated.
