Thinking is good. Too many people don't. When doing a loop test, unless the total is below the limit in Table 8.2 it's not technically possible for a single result to "prove" that the PEC is OK. Can't just assume a proportional split, eg 50/50 for PEC size = N size, or other split where PEC size smaller. philosphy neurosceince psyoogy wash u couress
