WorkPreference Help
Hello, I am trying to find the WorkPreference setting to put into my prime.txt so that I only get "PRP cofactor test doublecheck", or PRPCFD.
I thought it was 151, but ended up getting "PRP doublecheck" which would take way too long. You know what would be a wonderful addition to one of the Help pages? If the following page: https://www.mersenne.org/worktypes/ Had one extra column on it that would tell you the WorkPreference number corresponding to that type of work. Thanks in advance!

I still think that would be a great addition to the Work Types info page. EDIT: for reference: Code:

The problem is, there's only one George Woltman in GIMPS. PRP proof and certificate verification was correctly given priority over almost everything else.
