I reran the above using only 24 and came up with 70 unbroken and 296 broken. This shouldn't be too far off. Some variations may not be considered, but the runs still appear to break much more...

I factored just over 12k small primes out of the digit sizes for 92 through 97 so far today. Despite that 12k composites were removed, the region GREW by nearly 3k!

My earlier numbers are probably quite inaccurate! I may need to focus on 2^4 only, rather than 2(>4). I did a bit more study and it appears that 24 * 31 is specifically important! If the power of...

2.2M <70 when I checked a few minutes ago. Why would the db not pull out p1-p10 primes first if it was breaking down larger composites? Almost all of these are made up of <10 digit primes.

That explains why my Colab sessions weren't factoring 100%. I didn't look into why, but either YAFU wasn't returning factors less than 5 or 6 digits in size or my Python code wasn't retrieving them.
