MEA is a tool (written by Ferdinand Mosca) that analyses an EPD position set in STS-style assigning bonus points pre-defined in each EPD record.
temere.epd (Latin for random) is a 4975 position set created from a much bigger random EPD collection in an intelligent way with as goal to produce a reasonable reliable ranking list of engines with an estimated error bar of -25/+25 elo at fast time controls like 100ms, 250ms, 500ms etc.
Many engines don't obey the 100ms time control, either they play too fast (blue color) or use too much time (red color). It's therefore a bit hard to interprete the rankings. But things get better and better when we increase the time control.
