What goes around comes around

I've just done a LLTF on M65428453 from 74 to 75 bits, no factor found, but when I clicked on the detailed report, sitting at the bottom of the list with "no factor to 2^59", was ME

some 11.5 years ago when factoring was done on cpu's.

Why the factoring gap from 60 to 63 though?

For what it is worth, I just ran it from 60 to 63, no factors where found. PrimeNet gave me a "TF result for M65428453 was not needed".
I also submitted the results to Mersenne.ca
