Wow! That is a lot of work done there! Hat off and bow at James.
Some nitpicking: In the "p1 missed" you could also show who missed the factor, as you do in the "TF missed" report. Which report, by the way, should be called "factors blah blah TF" and not "factors blah blah P1". Crazy ideas (because they need some more work on your side): In the user factors reports, you could transform the headers into switches (i.e. toggle the "nfs/ecm/p1/p+1" on/off when clicked, and turn them all on when clicking "any", or something like that)  for example, if we want to see only the p1 AND p+1 factors, but not the others (yeah, nfs are quite troublesome, because they are so big, beside of the fact that they kill the table format, because the digit strings are so long, they are demotivating too , how can I fight for a 50 digits factor when some guys got a 200 digits factor? and who care about nfs? hihi, I want to turn them off!)

P1 probability calculator seems to underestimate stage 1 probability
https://www.mersenne.ca/prob.php?exp...000&b2=5000000 yields 9.918380%, while https://www.mersenne.ca/prob.php?exp...000&b2=5000000 yields 9.998854%.
Purely theoretical, but B1=B2=5000000 should have a higher probability than B1=2000000, B2=5000000. I'm aware that these formulas are based on experiments and extrapolations, but it always seems to underestimate stage 1 factoring probability.

The probability code is not my invention, it was written by Mihai and adopted by George.
Totally unrelated, I have just become aware my graph images haven't updated for several days, am away right now, will try to fix by Monday.

How difficult would it be to create a report that shows who found the most factors on one exponent? Second sort criterium would be the amount of "n factors per exponent" the user found.
I would assume the first place would be no more than three or four exponents in one page. @James: I looked at your export page and found no user records in that data to do it myself, was I overlooking something?

Not particularly easy. The data is primarily stored paying attention to the factor and exponent, only when you look at a specific exponent is the query performed to look up historical records as to whodidwhat on that specific exponent. This works acceptably well when querying a single exponent but isn't particularly friendly to broad queries against username that would be involved in compiling such a list.
