Hughes "retro fit" lifter not pumping up!

Ok i know i'm going to start a pissing match here, but. A lifter that take several minutes to bleed down and one that hold over night will make 0 Difference in HP, IMHO. Even if it took only 5 sec to bleed .010" off!

The lifter get it opportunity to fill or re fill itself EVERY rotation............How much time does the lifter have to bleed of at say 6000 rpm???? 6000 rpm divided by 2 =3000 rpm(Round Per Minute) divided by 60 =50
aka 50 times per SECOND......not much time to bleed off lift.
