Thanks for the info.
Would a tournament ever PLAN to do that though? Todd you mention not expecting players to leave the day open, but lets assume the professional side takes off on a path towards other pro sports, that doesn't seem crazy to expect, especially for a high profile event.
Super future conjecture time: If we assume we get to the point where the majority of the players are full time pros, it shouldn't matter to them that they travel on a Monday vs. a Sunday, aside from having 1 less day of rest between events, and I think if you can expect that, nobody would argue that we'd rather have a completed tournament by using the make-up day instead of cutting it short. Obviously would all be planned/communicated in advance of signing up, but I would think it's beneficial to have that backup plan, especially in severe weather prone areas/times of year.
Of course, professional DG isn't there yet, and there aren't fields of 90% full time touring pros, so it's all a moot point for now.
Haven't tournaments gone out early the day following an early-called round due to weather to finish it up before "beginning" their final round? That's not extending it past the "last day of the regular schedule rounds", but is an unexpected change of pace / extra strain on players. If a pro was given the choice 1) Play 2 rounds on Saturday, or 2) Play an additional make-up round Sunday, which do you think most people would pick (assume travel plans weren't a concern because they'd planned on it already)?
