Top5000 cutoff is >1 million bits, starting today (now 1.29M))
Sure thing. I emailed C.C. (and added a comment to the prime, too).
I put the asterisk in my morning message, but forgot to post the footnote. It is this: _______________________ *Note that the Top5000 cutoff plane will pass exactly 1,000,000 bits today or tomorrow. For the record, right now it is still at 999,400 bits' size, but the 1,290,000bits abominable primes keep on pouring in. Mark my words Next state of the Top5000 database will be that all primes from position ~1,500 to 5,000 will be ~1,290,000 bits.

Regarding the Top5000 cutoff or the "water line" it's now right on 1M bits:
Code:
4998 1089927*2^1000000+1 301037 p197 2006 4999 1064099*2^999999+1 301036 g412 2012 5000 32883*2^1000004+1 301036 p86 2002 5001 2043*2^999925+1 301011 L2998 2012 5002 851*2^9998541 300989 L1809 2011

...and here's the snapshot of sizes. Observe the plateau at k*2^12900001 (388290+a few digits); it will grow longer and then will take over the whole end of the list. As a corollary, after it will happen, the apparent rate of the last Top5000 number's size progression ("to the next 10000") will stop for maybe a year.

but but but... 97 is clearly above 11, even if they both have only 2 digits

IMO, that's a good idea! n=1290k will then take less than 10 slots.
But I doubt C.C. will conisider it.

Primes in positions 31885000 will now most likely simply squeeze smaller k's replacing with slightly larger, keeping the plateau almost unchanged.
