Default Using gfndsieve

I've started to look into using gfndsieve, because it is multi-threaded.


I have a question. Not a problem with the program, just curious.



When I start a sieve, it will say "expecting 192048 factors".


I will run a bit.



Then stop.


It will say 190376 factors found.
9624 left.


So the expecting is less than the actual.



How is the expecting calculated? Or is it just a guess that for a given amount of numbers in a range so many could be factors after others have been eliminated because they are even numbers?
