Re: [Bug-gnubg] Suggestion ( Equity DiffHistogram)

The temp map is a great new feature! It will likely surpass the need to use
the dice window (which I cannot do anyway since I am a handicapped windows

I'm having a hard time understanding where the equity values and "best move"
come from, since values in the temp map do not agree with the values in my
analysis window.

In the attached position, the temp map calls 24/13 the best move for a roll
of 65 (2-ply), but 2-ply analysis window shows 23/18 24/18 as better by .003
cubeful, and by .001 cubeless.  Also the 2-ply equity listed in the temp map
is +0.693, yet 2-ply cubeful analysis gives 24/13 an equity of +0.344, and
the cubeless equity is +0.468.

I thought for a moment GNUBG might not be normalizing the "temp map" equity
to the cube value, but +0.693 isn't quite the same as (+0.344 * 2).

Am I mis-interpreting the numbers, or is there an issue with the way GNUBG
populates the temp map?

I've implemented the temperature map. It should show up in the next
