That seems to say that the PD will only go into boost by itself if the batts are below 50%. So you need to push the button on the CW to get anywhere if you start the recharge at anything above 50%.
I don't know how it can tell when your batts reach 90% as the trigger for when to drop to 13.6v if you do go into boost without the CW (by starting the recharge at below 50%.) If you do hit the button, it will stay in boost for four hours, never mind the 90% AFAIK.
So essentially, if you start the recharge at above 50% and don't hit the CW button, you might as well have kept your 13.8v single stage Parallax (except for the 13.2 Float part if you use that.)
EDIT--and they say pushing the button is "not recommended?" Crazy?
Don't forget also that this all refers to the PD's time at 14.4v ("Boost") and has nothing to do with the battery's Bulk Stage and SOC when it changes to the Absorption Stage (when amps start to taper.)
The 14.4v will continue into the Absorption Stage, which will start at anywhere from maybe 60% SOC on up depending on the charging rate (size of charging in amps vs size of battery bank in AH.)
