In my mind we are compensating the guys because the allstar is a uniquely prestigious event and wrestlers miss regular season events to attend it. Its not about the fact that they win or lose.
I mean I'd argue it makes more sense to either have a bonus for both winner and loser or no bonus at all. Otherwise say the #2 guy beats the #1 guy at the allstar. Why would he get extra points there but not at a dual meet, or at brockport, or in the semis of midlands?
