The Independent Pool and Spa Service Association (IPSA) studied the effect of Title 20 on the use of 3/4 hp pumps. IPSA argues that this intermediate size of pump remains a practical and energy efficient option, and, as a result, should be exempt from the two-speed requirement.
Given IPSA's reluctance to embrace Title 20, their findings must be viewed with some suspicion. Nevertheless, the study makes an interesting and reasonable sounding claim. Theirs is a point that deserves further consideration and an independent study.
IPSA's study and conclusions can be found here: http://www.energy.ca.gov/appliances/2008rulemaking/2008-AAER-1B/public_comments/Residential_Pool_Pumps_and_Portable_Electric_Spas/IPSSA_Residential_Pool_Pump_Measure_Revision_TN-47889.PDF
