I don't think they apply to the torture test, only the actual Prime-finding program.
If you read the readme, it says:
You should not need to use the Advanced menu. This menu choice is
provided only for those who are curious.

SUM(INPUTS) error checking. Selecting this option will run an extra error
check on every iteration. This will slow down the primality test slightly.
Round off checking. This option will slow the program down by several percent.
This option displays the smallest and largest "convolution error". The
convolution error must be less than 0.49 or the results will be incorrect.
There really is no good reason to turn this option on.
