But how do you decide the records issue? Any games capped will be uneligible for records? So that is another loophole. I have never heard about capping PD in europe on any league level.
You could type forfeit into google and find some college level forfeits in US.
My weekly training is fine, why? because I can adapt and one week in training actually means nothing in the long run. I rarely have more than one WO in a season. I have tested walkover minutes in the past, so I kind of have the idea how to max out needed minutes.
I still think WO is a better solution than capping the winning margin and creating atrocious skilled players for the losing team. With walkover you know what minutes you will be getting. With scrub game you will have problems keeping your players on the floor -> eventually losing more minutes. You and me both do not know how easy/hard it would be to tweak lucky fans or the game engine.
