I have to declare that I've been in favour of PAR scoring for a while, it just seems inherently fairer - and much easier to report on - but I thought I'd throw a few ideas into the ring ....
PAR to 15 - a few posters have advocated this, but in my view that's too high a target. There are too many 'dead' areas in the game, and players are much more likely to chuck it in when they're too far behind. In general squash needs more 'crisis points'.
The comeback - it's a fallacy to say you can't make a comeback under PAR - if you're playing someone of a similar level and they win 7 points in a row from 2-all, there's an equal chance of you doing the same. Yes, it's harder than in standard scoring, but knowing that surely means you'll be trying harder, earlier.
Match length - yes, matches are shorter, since there are ovbiously less rallies. But since the target is less, and each point counts that little bit more, I'm sure that players make a little more effort on a few more rallies, so that the overall effect is less than simply dividing the time by the number of rallies.
The winner - I've analysed hundreds of games, converting from PAR to standard and vice versa, and in every instance the same player has won. The objective is to win more games than your opponent, and under both systems, the player who wins most rallies wins the game.
Stamina - if you're really concerned about it being less of a test of fitness, play best of seven.
Compliance - apart from sanctioned events that dictate the scoring, anyone is free to play whatever system they like. There's a lot of tournaments/leagues out there that play their own way, and there's no reason why that shouldn't continue. I don't know what the uptake of par to 21 has been in recreational badminton, but I'll guess that a lot of people/leagues/tournaments still play the 'old' way.
I think the WSF will vote this in, and although choosing an implementation date of 1st April seems a little perverse, I suspect it will all go rather smoothly. Impact on the chances of getting into the Olympics .... nil.
