Here's a relevant OTT post from 2011 where "Sqidget" weighed in with "Artisan" on a discussion that included estimating hydraulic availability at the FEL and the BH connections.
In it, Sqidget notes that the max output from the pump is 6 (it's 6.2) gpm and that there's a flow priority valve that sends some of it off to the HST+PS, leaving "likely 3-3.5 gpm" available at those points. So, it's in the range of demand for the Samurai. The impact of being low is, according to the Samurai rep, is a slightly reduced ability to cut through thicker (up to 1.5") branches.
So we're getting closer to an answer. Not exactly definitive, but an estimate from a purported authority.
