Thanks James for the new table. I assume that there are factors found by him using ECM with 71 bits and with more than 72 bits that are not shown in this table.
PS: It appears that the number of factors with n bits is about k / (n1/2), where k = 50,847,534 is the number of primes below 1,000,000,000.
