Default SequentialWorkToDo switch in Prime95

In undoc.txt, I find the following information.

The program used to do factoring and P-1 testing on exponents even if
they were not the first entry in worktodo.ini. The rationale was that
if the number had a factor, the server could be contacted and another
exponent reserved. This avoids the possible scenario where the LL test
for the first worktodo.ini line completes, a factor is quickly found for
the second line in worktodo.ini and the computer now sits idle until
the server can be contacted. This behavior was confusing, especially
to newcomers. To restore this old behavior add this line to prime.ini:
SequentialWorkToDo=0
One added benefit is time estimates in Test/Status will be more accurate
because we'll know no factors will be found and the LL test must be run.
I have two computers, One solely for LL, and one solely for factoring. My question is if in the factoring computer's worktodo.ini I have the following entries:
Test=33xxxxxx,60
Factor=23xxxxxx,57
Factor=23xxxxxx,57
Factor=23xxxxxx,57
Factor=23xxxxxx,57
Factor=23xxxxxx,57
Factor=23xxxxxx,57

and in prime.ini I have SequentialWorkToDo=0, will Prime95 go on to factoring the factor assignments after factoring and P-1 of the Test entry, or will it do the LL on the Test entry before going to the Factor assignments?

It will factor everything first.

It will do the LL test first - I think.

That's what I suspected, but I'll find out for sure in a couple days.

If you had:

Test=33xxxxxx,60
Test=23xxxxxx,57

It would factor the second exponent before LL testing the first exponent

This is useful if you are trying to get the max out of your machine. I ran into this when I went on vacation. I set the switch and during P-1 for the second exponent it found a factor and I was able to get a new one to have the machine work on while I was away.

Or you can go into the PrimeNet dialog and ask for it to queue more days of work. If P-1 factors the second exponent, it will go on to a third exponent. You would not want to queue too many days of work, but you could double the current value to ensure that you get another exponent.

Yep, that's what happened, as suspected.
