What is the conclusion of this discussion? Were the previous results of +160 elo or so per doubling down to the use of fast time controls which is not appropriate? In light of the advancement in hardware since 80s, isn't a 6sec per move not enough to match the long time control used at the time the +70 elo per doubling is reported ? Maybe the number of opponents with different style of play is not enough that made the results obtained similar to what could be found in a self test. I am just speculating but there must be a reason that can be pinned down..


I'm unsure of the conclusion. The tentative conclusion is that the maximum ELO is in the low to mid 4k range but ELO is a slippery dude and it will depend a lot on what assumptions you make.

If we can figure it out then it would be fun to run the test to a significantly deeper level.

I am not sure of what the significance of that number is. Obviously elo is not bounded if you use the elo model that relates elo difference with winning percentage 400 * log ( w / (1 - w) ). If you win 100% your elo is infinity. It seems that what you obtained is a fit for your data and an extrapolation for a certain degree of confidence. Clearly over-fitting and similar problems give you very different results (eg the first extrapolation of 10000 elo as max). Why not use the standard elo model as I gave above instead and calculate elo diffences for a give CI and add it to the elo base 1500 f.i.
Anyway I thought that was an aside discussion. I am more interested in what can be concluded (learned) about from the contrasting results.
