The knockout format is a big difference and what if there wasn't a PTS game? Would you think different then, because to me it seems that you're more against mixing TT with PTS than having something against the PTS system itself.
All I'm saying is let the players decide and I don't see how you're 'saving' TT with bringing one flawed system (set ratios) to replace another flawed system (PTS).
I think predicting scores is not as related to TIPPING as set ratios is and I have said that several times over. I am also strongly against the combination of the two games. Those are my two reasons, and they both contribute equally to why I am so against PTS becoming an even bigger part of this game. I think both of them mar what is otherwise a very good game. Predicting scores takes very little tennis knowledge... it is pure luck whether a set ends up 6-4 or 6-3 half the time, as I've said. Knowing whether it is likely a player will win in 2 sets or 3? That takes a little more tipping knowledge, and that is what is at the base of my proposal: keeping this about tipping and not about luck. Like I said before (somewhere...), PTS had a poll up about switching to knock out format... if PTS had done that, what would the difference be? Nothing. These are supposed to actually be different games, not just different formats.
Also what about situations in PTS where this happens:
Match: Mathieu def Coria 6-1 0-6 7-6
Player A: Mathieu 6-1 6-4 (10+0+1+6)=17
Player B: Mathieu def Coria 2-6 6-2 6-4 (10+5+1+0)=16
Player A wins while in my opinion Player B had a far better idea of how the match would go.
In my opinion here, player B is probably the better tipper and would deserve to go through, but instead they lose. Just to know show how unfair PTS can be sometimes as a TB method in a tipping game.
