Should I TF 70—>73 or 72—>73?
Which is better? I thought it might be better to work the "last mile" 72—>73 since that helps get the exponents out of GPU to 72 and back to the PrimeNet pool.
But is time better spent starting from 70 (with StopAfterFactor=2 to bail out as soon as possible after finding a factor) since the chance of finding a factor is higher at the lower TF level, although clearing fewer exponents out in the same amount of time? Tell me what to do...

First, is not optimum, you have more chances to find factors at lower bitlevels, for the unit of the time spent doing TF. Second, is not "orthodox", skipped levels tend to be forgotten and never done. Third, you do it for free, as you will not be able to report it, PrimeNet does not accept "noncontiguous" bit ranges. So, you waste the time, no credit for you. If the exponent is TF to 70 on PrimeNet's DB, then please do 70 up.

Choose to do what you enjoy most. At the end of the day all the current candidates need to go up to (at least) 73. Some get fixated on finding factors, and/or the "GHz Days Saved" metric so only go one level. That just means that someone else has to step in and do the rest of the work.

OK. I see the logic of working on the lowest exponents. I'll switch back to "What makes sense" option.
