For 26.3M, I guess you'll have to strike me out because Chris is finishing it up. @Chris: Thanks for releasing the other two ranges for me.

I have found that the probabilities given by way of James' specialized Worktodo generator give quite different probabilities, compared to mprime during runtime calculations, compared to James' deep drilldown iif a factor is found. I'm mostly just wondering if anyone else sees this, or if I'm not understanding things deeply enough (very high probability of the latter). P.S. BTW, we seriously overshot 13.7M. Sorry about that. P1 was more successful than expected.

1. mprime is most correct; its calculator is getting attention with recent updates to the P1/ECM/P+1 algorithms and comparisons to gpuOwl. 2. James' exponent pages (the deep drill downs) report values fairly close to the mprime probabilities 3. Something weird happens with the "worst bounds" page. It's not quite as dynamic as we might like; exponents can only be removed (when someone does an improved P1). Perhaps it should be possible for exponents to join the list when the P1 bounds become "small" relative to the amount of TF that's been done.

All I use is: Actual Probability = Pr(new)Pr(old). If the prior P1 had a 2% prob and the new P1 has a 5% prob then isn't the new P1 actaully expected to have a net 3% success rate??

As in my formula above: Actual Probability = Pr(new)Pr(old). My overall average success rate is about 0.25% higher than this. Though it does seem to be a little closer with the new version of P1 (which I assume includes new estimations). Of course I have really bad ranges and also really good ones (like your 13.7)....but overall....

See my formula in response to masser's response above. I'm waiting for him to tell my if I'm mathematically confused. :(

RDS once reminded me about conditional probabilities.
When P1 is relatively small, P2P1 is a good enough approximation.
