Regulator installed Is this about Right?

Installed my ASR on my .25 AT 44 long. and tinkered with different settings on regulator and hammer spring combos all weekend. after various settings and a good workout from the hand pump. i settled on my regulator set at 165 and my hammer spring at 5 turns out. with a 5 shot avg of 819 FPS, and a ES of 5 and a 46.27 FPE with H&N Barracuda's (my jsb's won't be here till later this week.) so this morning i ran it through Chrono and sighted in at 38 yds and had to only adjust 5 clicks up on the scope. my left to right was still good. and see how many good shots i could get. i first tested nine shots. which my avg fps stayed the same and my es went up to 8. so kept shooting to see where i would start to fall, and at shot 14 is where it started to drop. but still made all 19 shots in the bullseye. so am leaving it there since i normally just do my fills after one magazine anyway. could i do better i dunno but i do know its better than before the regulator and i haven't done any valve mods as of yet. am i where i should be or can i get more. I'm kinda figuring if i get the JSB's to group well it will be a flatter trajectory and same fpe. Any thoughts?

In a power tune that it looks like you have ... a lighter pellet is going to shoot faster and flatter bun in all likelihood not do any more shots and sadly might be a few less.
PCP's generally are most effecient with heavier pellets ( To a point pending state of tune )
Power ( FPE ) likely to also be 2-3 ft lbs lower.
Here a bid of data on my .25 cal Regulated BAM 50 with same tune tho differing weight pellets.
SAME settings used on all tests .... YUP more weight = More pellet energy
EUNJIN 43.2 gr H&N Barracuda 31.02 gr JSB KING 25.4 gr
740 fps 50.3 ft lbs 840 fps 48.5 ft lbs 908 fps 46.5 ft lbs
