Is it possible, that your query ignores the ones with factors less than 67, instead of making them appear like they are TFed to 67, and thus not making the 67 range be <=67?

Are you planning to TF some exponents that have known factors to higher bit levels? Besides TJAOI's efforts, you should also keep in mind the P1 bounds (if you trust them; there are reasons why you might not) will occasionally make TF irrelevant at lower bit levels. For the very low exponents (say, < 3M or so), ECM makes additional TF even more nonproductive. Last fiddled with by masser on 20210313 at 15:45

Now available at https://www.mersenne.ca/factored_counts_report_pm1/ with separate reports for factored and unfactored exponents.
You can again access the latest report via https://www.mersenne.ca/factored_cou..._pm1/?latest=f and/or https://www.mersenne.ca/factored_cou..._pm1/?latest=n respectively. I will investigate this.

The ratio is most probably not 1:1, but close enough, I would say. In this range, there are not many TFable exponents that fit my work criterion. I also have this weird uncomfortability with ECM, because I don't have a complete idea of how it works, only a rough idea.

Top 500 totals in each of TF, P1 and ECM. Interestingly the last column (GhzDays/Factor) does NOT vary a whole lot. Code:
Work GhzDays Attempts Succ. GD/Att GD/Succ TF 134655501 34272856 710178 3.93 189.61 P1 790280 114778 3811 6.89 207.37 ECM 181452 356771 1150 0.51 157.78

Maybe the best way to test would be to parse the list of known factors and compare the minimal work amount for TF and P1, as there is a bias towards the TF in the factoring process because the TF is done first.

Bounds in the P1 are pretty straightforward, but because ECM is based on chance, the straightforwardness goes away.
