Re: Re: Re: [Bug-gnubg] small suggestion and questions

I tend to agree with you. However, we already have the error-rate
numbers to ensure long term consistency. The error-rate to error-class
translation is there for a single purpose: to make it easier to relate
the numbers to the real world. If the real world world-class players
are considered world-class in checker play and expert in cube-play
then I think that this is inconsistent and arbitrary. We choose the
thresholds when we translate from error-rates to error-classes and
since cube and checker play errors are not comparable the way gnubg
calculates them, choosing the same thresholds is both inconsistent,
arbitrary and in denial of empirical data.

If we in ten years find that the thresholds need adjusting, we may do
so, since we still have the error rates that are consistent over the
years.
