Are all FargoRates created equal? If a 700 who exclusively plays on a bar box matched up against a 700 who plays exclusively on a nine foot table, would the match be equitable on a both tables sizes or would the nine foot player be a 700 on a nine footer and the bar box player play at a 650-ish level on a nine footer and vice versa?
The match would probably not be so equal on either table. One person is familiar with the equipment and the other isn't. I think there would be a gap like you suggest but my guess is closer to 25 points rather than 50. This is a familiarity issue. The two players are equally skilled, and if either played for 100 hours on the unfamiliar equipment, they'd perform at 700 speed.
