After running my Nvidia GTX 950 for 30 days, I was able to find more than 60 factors in the ranges 71>72 bits, 72>73 bits and partially in 73>74 bits, reducing the number of unfactored Mersenne numbers in the range 987.9M to 1999.
According to https://www.mersenne.ca/status/tf/0/0/4/98700, the number is 2001, but this includes the factored numbers M987977819 and M987976229 that were found after 00:00 GMT today, so the current number is 1999.

3 Year Project Update
It is 3 years since I took my first set of stat for this subproject.
I didn't personally start working on it until 3 months later but others are always making progress. Since last update (May 12) 11 more ranges cleared: 3.3, 30.6, 40.0, 45.3, 45.8, 50.2, 52.3, 52.9, 53.2, 53.9, 56.6 And 8 bonus ranges: 61.6, 65.4, 69.8, 71.8, 75.2, 78.2, 81.4, 86.3. The 6 cleared in the 5x.xM and all the bonus ranges are a HUGE thanks to someone (who prefers to remain anonymous) who took up my challenge and cleared most of the STUBBORN ranges I mentioned a few posts above. In the last 3 years: 177 total ranges cleared or 35.61% 14 Ranges with less than 20 to go. 945 more factored (24,026 total)....43.50% total factored. Continuing to get lots of great help. THANKS Thanks again for everyone contributing.

43 down, 200 to go
I've worked on the 14.0M range for the last 4 months: 43 factors found, with a mix of TF, P1, and a little bit of ECM. We now have 200 to go for the under 2000 goal. If everything goes according to plan, I should complete this range in about 2 years.

10M to 11M range
I have moved the entire range to 70bits and found about 300 factors with mostly TF (about 250) and P1 (about 50). It took me about a half year.
1028 factors left to find.

After I finishoff this range, I want to do the stubborn 42.6M range.
I was also thinking if it wouldn't be easier if instead of less than 2000 unfactored exponents we aimed for something like 40% unfactored. Well, it would certainly be easier, but the real question is whether it would be good enough...

PS if you check for recent factors found under 80M you'll notice someone putting a lot of GPU power to the stubborn ranges. How long they stick around and whether 42.6 is in their sights remains to be seen. Thanks again.

Also watch for where TJAOI is turning in factors. I think most recently it is in the 67 bit range. I saw some recently, I don't remember what exponent level.
