Unregulated Marauder shot string/velocity per fill...?

With my regulated .22 Marauder I get 60-65 shots before the velocity begins to drop off at all. I've read where an unregulated .22 Marauder will shoot a 16 gr. pellet at about 1000 fps. From what I understand, it will allow roughly 30-35 shots per fill. Does this "per fill" mean at a relatively consistent velocity before significant drop off? 

I'm still new to the PCP side of things and trying to learn. Thanks in advance for the patience...😁
 
Shots per fill generally means the number of shots you can get before the velocity of each shot falls significantly below the average of all the shots in the string. The shot string, when graphed will make a curve (usually) which rises in the beginning, levels off in the middle and then drops off on the end. Usually when talking about the shot string the shooter will specify how much deviation from the average he is accepting to get that number of shots. So for example a shot string which has an average velocity of 900 FPS for 30 shots with a 2% spread means that all 30 shots in the average fall between 891 FPS and 909 FPS. That would be pretty good. That was an example and I have absolutely NO CLUE what a Maurader can be expected to do. Others will chime in with that no doubt.

That was a good explanation oldspook. That means that I was thinking about it correctly then. Thanks for the thorough and quick reply........I appreciate it.

Usually the curve rises and falls is completely right. But if one fills to the proper PSI they can start off right in the middle of the curve so will get a number of shots at near the same velocity before the velocity drops off rather abruptly for the most part. Your number of shots will be lower but more consistent. This is the sweet spot many with unregulated guns will tune to. So you will be able to get a number of shots at a higher velocity than with a regulated gun. But with a way lower shot count.
