A fixture is listed in the UPC's Table 610.3 with a total WSFU value of 4.0 (covering both hot and cold combined). Per the UPC's rule for splitting a fixture's load between its hot and cold branches, what is this fixture's individual hot-water WSFU load?
Not quite. The answer is B: 3.0
Table 610.3's notes say the separate hot and cold shares of a fixture that has both connections may each be taken as three-quarters of the fixture's listed total. So a fixture listed at 4.0 WSFU counts as 4.0 × 0.75 = 3.0 WSFU on the hot side (and 3.0 on the cold side).

The Seattle copy marks this table's heading as a city amendment, and WAC 51-56-0600 does not amend it, so we treat note 3 as the base 2021 UPC rule. The exam supplies this table at the desk.
