    Will do next time I have the Chrony set up, also could try on single shot to see what goes on. I may well include in target practice rather than just wasting pellets.

    Yes, it is an interesting one, it looks like I made that graph up! I did not really spot it from the raw numbers, but the graph really shows it up.

    How bizarre. I am not familiar with the 10 shot conversion, but is it the typical probe through the mag affair, with the probe finally sealing within the breech block/barrel itself? If so, it ought to make no difference to sealing which shot number in the magazine it happens to be, also the major drop between mag changes coupled with a gradual increase does not sit well with the possibility of poor sealing, I would expect more erratic behaviour.

    Yes, the probe/o-ring just pushes the pellet through the mag (all 10 pellets are held by a single large o-ring), which seats in the breach just like the single shot system. The results are certainly weird.

    Bollards! Operator error. The F1 Chrony readout of 'stored values' shows the last shot first, and the first shot last. So reverse all the reading and the graph makes a very nice curve!

    On a positive note, D: Very nice work with the coloured graphs.

    When I use my Chrony, I need a pencil and paper to record the scores.

    Hee hee hee!

    Never mind, sir, all sorted now. Nice little graphs there, although the earlier one looked far more entertaining.

    And there I was getting ready for some nasty gremlin theories at work inside one of these pesky pffft guns from the dark side!

    That's what had me going at first - a very mysterious thing! At least I know the gun and the Chrony are fine...it's just me that needs examining!

    Damn! You spoilt all the fun. Could have let us simmer and ferment for a few days!
