I have been playing some teaching games against a guy rated about 400 points lower and it seems maybe he has learned a bit, his rating has gone up about 100 points.
My question is this: I am about 1650 and he averages about 1250 so a 400 point dif.
So far we have played 57 games where he won one game and lost the rest.
Given our 400 point difference, am I under performing for that rating difference?
Also, just on the math involved, would the win or lose % be different for that pairing vs if I played the same number of games against MY 400 point difference, in this case, me playing a 2050 player, do the numbers work out exactly the same or are there differences based on the different numbers even though the difference is the same?
So it looks like one loss out of 57 games gives me a loss number of 1.75 percent or thereabouts. Is that where I should be given the rating difference of 400 points?
