No, what you suggested was to use different fill levels.
What I suggested was to use the same fill level, that would hopefully produce a similar spread of MVs, to check just what difference the fluctuating MV had on point of impact.
A different fill level would change where the "flat" portion on the graph began.
For instance if I fill my unregulated Daystate Huntsman to 190 bar the chrono shows a starting velocity that then climbs over a number of shots to that point where the velocity evens out level if it was plotted on a graph.
If I fill it to 170 bar then the first shot is at the start of that flat area on the graph and I will get 50 shots plus/minus 4fps. After that velocity starts to drop.
What I wanted from Shootist was a real world indication of how the impact point changed when using his current fill pressure and valve opening setting with it's current fluctuations in MV.
Ideally the test should be done bench rested on a sheltered range in calm conditions to eliminate wind effects and Shootist has access to that on his club 50 yard range. (Not withstanding the wind
)
