Totally disagree. A player than can give me 3 games to 8 on a big table with tight pockets cannot give me that game on a bar box with buckets.
If you play a majority of your league play on bar tables, your Fargo rating will be higher than someone you should play even that plays their league on big tables.
Ok but who wins if you both play with no handicap?
I think that the better player wins more often on both tables. You might have a slightly better shot at beating the stronger opponent on the easier equipment but over distance the stats probably even out with not too much difference.
I do agree that this is one MAJOR point with any rating system in pool. The disparity in equipment is something that is surely hard to account for in some situations. I have to think that Joe Average bar box player is going to have better performance stats on bar boxes than he does on big tables. If he plays 100 games on the big table he will likely lose a higher percentage of them than he loses on the bar box.
But how big a percentage difference? Enough to really matter?
In chess and just about every other sport the playing conditions are close to the same. Even in tennis which has grass and clay there are only two main surfaces. In pool you have 7, 8, 8.5, 9, 10ft tables with many different pocket cuts and depths, different cloth types....to ignore all that and say that a player is the same player on all equipment is naive. It's simply not true. I have beaten several pros and several shortstops on bar boxes in short races. I have never beaten a pro in a serious match of any length on a big table.
I would NOT gamble against the pros and shortstops on bar boxes and certainly not on big tables. I have donated....but despite having a bit better chance to win games I still have little chance to win sets.
Right now my established Fargo rating is 25 points higher than another local established player who is a good two balls better than me. Mine primarily comes from a round robin tournament several months ago where I won a lot of games against players my speed and higher.
I expect that this has to even out and our ratings to be more reflective of our real skill disparities as we both play more games. At least in our case 200 games has not been enough to accurately rate us.
