Right - in case it's not clear, Fargo rate is not related to match wins, it cares about games won/lost. E.g., if a 590 pays 10 races to 9 vs other 590s, the expected outcome in games is something like 90-89. If they go 90-11, their fargo is going to go up.
So if your Fargo is 595 but you actually play way better and want to keep it QUOTE]
This is very dangerous to do if your opponent is actually close to your ability. Let it get to 8-7 or 8-8 and your brilliant idea to keep it close might well lead to a loss.
Where is can work is for very strong players against much weaker opponents in an even race. If a 699 is playing a 550, he can probably easily let the 560 get to 6 games and still be confident of a 9-6 win (which would help the 699 stay under 700, as the 699 would be expected to win bigger).
