Mike, you're right. I still haven't finished my 2500-3100 range, and the factors in my range were the ones previously been found by Louie.
I was away from the pc sievig that range for the last couple of days. I guess the remaining part (2762 - 3000) is about to finish today. I'll take a look and submit the factors tomorrow. But, my estimate is that there should be roughly 300 factors there. So, there is still 500 factors missing.
Let me take a look at possible gaps below 3T too. I'll let you know if I find something.
EDIT: Mike, my internet connection is very bad for the last couple of weeks since the earthquake and I could not download lowresults file. But I found a version of it that I previously downloaded, and checked for holes there. There are four instances where the density of factors are abnormally low. These might have been patched later, but since they are very small ranges (1.1G in total), I guess it's worth resieve.
Mike, could you please check these out (especially the first one).
1.486G-1.619G (or 1.48-1.62)
4.769G-4.803G
49.957G-50.576G
55.668G-56.019G
PS: 1T-3T seems hole free.
