I like the concept. I pretty much ended up with an experimentally
derived ranging in 3.0 that is not too different. I'm willing to give
yours a look:
current:
body BAYES_00 eval:check_bayes('0.00', '0.01')
body BAYES_05 eval:check_bayes('0.01', '0.05')
body BAYES_10 eval:check_bayes('0.05', '0.20')
body BAYES_25 eval:check_bayes('0.20', '0.40')
body BAYES_50 eval:check_bayes('0.40', '0.60')
body BAYES_75 eval:check_bayes('0.60', '0.80')
body BAYES_90 eval:check_bayes('0.80', '0.95')
body BAYES_95 eval:check_bayes('0.95', '0.99')
body BAYES_99 eval:check_bayes('0.99', '1.00')

I think some of the ranges are too empty. Let's try:
0 to exp(-8)
exp(-4) to exp(-2)
exp(-2) to exp(-1)
exp(-1) to 1-exp(-1)
1-exp(-1) to 1-exp(-2)
1-exp(-2) to 1-exp(-4)
1-exp(-4) to 1-exp(-8)
1-exp(-8) to 1
0.000000-0.000335 39.046
0.000335-0.018316 0.598
0.018316-0.135335 0.699
0.135335-0.367879 0.352
0.367879-0.632121 4.717
0.632121-0.864665 1.511
0.864665-0.981684 1.739
0.981684-0.999665 2.450
0.999665-1.000000 48.888
That's better. Maybe we could...
