It likely can, but I'll need to tread carefully with that code. I'll see how possible it is (especially since my previous fix for full-bitrange factors doesn't appear to have worked as intended).

So I've looked at the manual_results code and you are indeed correct: TF credit is only given as far as where Prime95 would have found the factor. The TF-credit calculating code is somewhat buried...

In terms of GIMPS, stopping immediately after a factor is the efficient thing to do, (it's not prime, QED). Somebody might eventually extend factoring, but they're already "wasting time" (in terms of...

If you complete the bit level after finding factor it should give full credit, if you stop after factor found then scaled credit is appropriate. I'm out of town for 2 days but can double check the...

It's harder to see from the data since many people (most?) will stop factoring immediately after finding a factor, so unless the factor pair is in the same class the second factor wouldn't be...
