I went to the source at Frasca...it should be logged only as
simulator time, and not as total time.

If you quoted them accurately, then your interpretation is incorrect.
They merely said it's more convenient to log it in a separate column,
because *some* people want you to break it out. The word "should"
doesn't apply here, because "Total Time" is not defined in the FARs
and therefore there are no rules about logging it.

They are also wrong by saying that the time doesn't belong on an 8710.
It does, and in the Total Time column, because what it asks for is
Total PILOT Time, and FTD time is PILOT time.
