I would like to propose three rules to reduce confusion, if OP and others agree:
1) If you are writing odds in decimal form, always use the standard form(as opposed to the one used on MTF). So, it would be Del Potro@1.3 or Isner@3.97 instead of Del Potro@0.3 or Isner@2.97
2) Always mention the match(or the opponent) not just the outcome.
Isner to win first set 7-6: $email@example.com
Isner to win first set against Del Potro 7-6: $firstname.lastname@example.org
Del Potro-Isner: Isner to win first set 7-6: email@example.com
It wouldn't matter most of the time, but on the few occasions that a player plays two matches in a day, it would.
3) Each result should be rounded to the nearest cent(two decimals).
I agree with these proposals. I guess I'll be using fractions myself, as this is what I'm most used to. But for those who want to use decimals, just copy exactly what you find at the bookie site, not
what you can find at vBookie.
