Excellent score, John! 
For what(ever) it's worth, below are my testing notes of a couple GPs I owned when they were somewhat available in the U.S. I was impressed with both (calibers).
.177 Brocock Grand Prix single-shot PCP
7.9gr JSB Express, 200 BAR charge, 18 shots- Low= 762, High= 776, ES= 14, SD= 4, Average= 768 FPS / 10.3 FPE
.22 Brocock Grand Prix single-shot pre-charged pneumatic
14.3gr JSB Express, 2800 PSI, 32 shot powerband- 547 / 576 / 29 / 3 / 564 / 10.1
Simple design + good materials + solid construction = the right equation for a nice PCP pistol.
12/11/09 Five consecutive five-shot groups at 50 yards averaged 1” c-t-c (best = .66”).
Shot 41/42 at the December Yegua FT match; unfortunately the winner shot a perfect 42! Ouch!
Also FWIW, the friend that beat me in that match did so right after I'd adjusted the trigger on his FX Ranchero to a very impressive, match-grade let-off. That, after having monkeyed (a LOT
) with my Grand Prix trigger trying to achieve a lighter break. Although plenty crisp, I couldn't get it quite as light as I'd like for FT competition 
; which is to say "almost telepathic".
Last FWIW (for now), noticing the 2009 date in the testing above, that was shortly after I founded Pistol Field Target competition. Both he and I went on to become multiple State and National FT champions in Pistol Field Target. Guess that one-point loss is what I get for helping my toughest competitor adjust his trigger!
Here's a photo of Mike... probably taken when he realized he beat me-
Not sure why every time I see that photo I think of the adage"No Good deed goes unpunished."
