UPDATE  January 14, 2018
1,547 !!! more exponents factored in the ranges of interest...0  59.9M GREAT PROGRESS
(In ranges where there are still more than 1,999 unfactored. 4 more ranges cleared (now below 2,000): 45.0M, 48.1M, 51.3M, and 59.9M 11 ranges within 5 or less to go. Good news (HAHA): There will be no February update (Vacation) 
6 months
And I've found 200 factors for this little subproject so far.

You got some work to do
There remain 21,535,921 unfactored exponents below 1G, so even if GIMPS keeps up with the current pace of ~160,000 new factors per year, you're looking at another 10 years to get that number below 20,000,000 :unsure:.
I haven't even factored in that is gets increasingly harder to find factors... 
I am doing some heavy ECM on a few candidates between M100000 and M220000 chosen from [url]https://www.mersenne.org/report_ecm/[/url] but I don't want to step over someone else's work...

Those higher (with a few exceptions) will happen naturally with the given TF limits. We need about 40,000. Last year over 10,000 were found. Granted this range even more so will take progressively longer but likely much less than 10 years. 
Since the 1st of February 2013 we have found nearly 1,400,000 new factors. I am pretty confident it will take no longer than 67 years to get to under 20M unfactored.

2 Months later and great progress  March 16,2018
2,759 !!! more exponents factored in the ranges of interest...0  59.9M
GREAT PROGRESS (In ranges where there are still more than 1,999 unfactored. 13 more ranges cleared (now below 2,000): 2.0M 35.6M 40.9M 42.5M 44.8M 45.6M 45.7M 46.2M 46.8M 51.7M (51.xM is now complete) 55.0M 56.0M 57.8M 6 ranges within 5 or less to go. 
April 15 Update
3 Ranges cleared: 44.1M, 54.6M, 57.7M
910 Exponents Factored 5 ranges within 5 or less factors to go. And 6 more with 10 or less factors to go. 
May 15 Update
3 Ranges cleared: 44.0M, 44.2M, 57.4M (34/497 Cleared since Sept 24, 2017)
601 Exponents Factored (8,770 since Sept 24, 2017) 6 ranges within 5 or less factors to go. And 6 more with 10 or less factors to go. 
50M Range Update
This has been my current focus though others have certainly helped in this range too.
As of today all 10 5xM Ranges have under 20,000 unfactored. 69 5x.x Ranges have under 2,000 unfactored. Of the 31 remaining ranges I hope to get 20 of them under 2,000 over time. The last 10 ranges, which for some reason have more than expected unfactored, may have to remain. :(
