All teams equal, i.e., each point is a 50-50 tossup
No distinction between Singles and Doubles
No Serve/Receive advantage
Of course, none of those is true, in reality.
For example the #1 7-point Trifecta finishers (tie) are 1-4-2 and 2-4-1 (mirror images), but we KNOW that Post 1 has a slight edge in Singles, and Post 2 in Doubles. So, the table results will vary due to all of the above conditions (maybe more) as well as just luck.
So, back to your actual question, it is nearly impossible to make a full answer because:
Frontons (with very few historical exceptions) do not separate Singles & Doubles stats, and 7- and 9-point results are combined to further mash up the results.
Also, the frontons often change their performance formats re:
# of games
Singles or Doubles
7 or 9
greatly complicating historical aggregation. Craig G took his best shot elsewhere in this thread.
I could go on forever with this. So, I think your best bet is to study those tables and combine with whatevere observational factors you can add.
