Previous ranges 54.5 M (B1=B2≤730,000) and the second half of 55 M (B1=B2≤690,000) should now be finished and I am "unreserving" them.

Report for range 54.4 M (B1=B2≤730,000): 0 factors found in 18 attempts (0%). Expected probability 3.81%~3.83%.

Report for range second half of 55 M (B1=B2≤690,000): 0 factors found in 12 attempts (0%). Expected probability 3.89%~3.92%.

Currently working on:
- the first half of 56 M (B1=B2≤690,000)

Now intending to work on the exponents in the second half of 56 M that has B1=B2≤700,000 [B]and[/B] without a DC.
As most of the exponents will be in Cat 3 and higher, I will reserve every exponent as TF before I start my work. If you see an exponent that is not currently reserved in the Primenet system, then it simply means I am not working on it. Declaration here is more for the recording of progress.

Currently colloquially "reserved":
- the first half 56 M (B1=B2≤690,000)

Currently intending to do (will Primenet-reserve every exponent before I actually start working on it, so you don't have to avoid anything——there is no risk of me poaching your factor):
- the second half 56 M (B1=B2≤700,000)

Report for the second half of 56 M (B1=B2≤700,000): 2 factors found out of 35 attemps (5.71%). Expected prob. 3.93%~3.94%.

Now intending to work on the exponents in the first half of 57 M that has B1=B2≤700,000 [B]and[/B] without a DC. I will reserve every exponent as TF before I start my work on it, so you don't have to avoid them.

Currently informally "reserved":
- the first half 56 M (B1=B2≤690,000)

Currently planning to do (will Primenet-reserve every exponent):
- the first half 57 M (B1=B2≤700,000)

I'm finishing up the exponents in the 13m - 13.1m range where B2 < 1.9 million.
