It's difficult because one could win via concession at any time, or by reaching three points. For sake of estimation lets say that all our wins come from concession at zero points, one point, two points, or by reaching three points, in something like a 10/40/40/10 split:
Step 1: MULTIPLY the number of wins by 1.5; this gives us the number of points dedicated to wins.
Step 2: SUBTRACT the number of points dedicated to wins from the points total; this gives us our points dedicated to losses.
Again this is difficult, but less so, because losing naturally at one point is the same as conceding at one point, and you will never lose at three points. Lets assume that the loss split is 20% zero points, 40% one point, and 40% two points, due to the frequency of EX usage on both sides.
Step 3: MULTIPLY the number of points dedicated to losses by 0.6; this gives us an estimated number of losses.
Step 4: ADD the number of wins to the estimated number of losses; this gives us an estimated total number of games played.
Step 5: DIVIDE the number of wins by the estimated total number of games played. MULTIPLY this number by 100; this gives us our estimated winrate.
