Available Ranges suitable for P4s

This is a set of ranges that are suitable for P4s. P4s do really well on factoring about 64 bits and not well at all under 62 bits. Also, please check the reserved ranges thread to make sure there is no overlap.

Code:

Start       End              Bits done
25M       25.01M             64
28M       28.01M             64
33.61M    33.64M             64
33.66M    33.67M             64

The LMH status shows that only about 0.2% of the remaining exponents are factored to 64 bit. So it's still a kind of discrimination against P4-users who want to join LHM.
Therefore I suggest to reduce the suitable bit depth to 62 bit. 62 to 64 bit status have about 1.5% of the exponents and a lot of others are in work to 62-64 bit.
Also important to point out that all this is only a recommendation and not a restriction for P4-users.

After a quick view to the nofactor file I see the non-reserved ranges (all 62 bit):

28.0-28.1M
34.0-34.05M (some 60 bit left-overs )
75.0-75.1M
