here is one - 1000 yrds - shot during a comp. first shoot at 1000 after 100 yrd load dev.
Do ya reckon its case capacity throwing the shots high? what would people do. The group isn't centred as I was testing the load so apart from calling the wind and adjusting the scope no change were made. A lot of F class keep vert under control by clicking.
What to do - was it me, the load, conditions, hold, what?
There is very little that can be deduced from that group. Perhaps a plot of elevation V time will show a trend.
Why not repeat it while measuring V and also recording the wind setting for each shot. You then have something to go on which may preclude certain causes.
BTW, after a few hour's searching I cannot find my work on measuring V from different volume cases. I have not entirely given up. Ironically, the critical plot was actually part of a previous post on this site I did ages ago but I cannot find it in the archives.

Thanks for the reply(Peter, Albert, Gsells) - I posted it up as I thought it was a group that represented what many often see and discount in either load dev or the comp and which I think is one example of why you posted originally Peter.
For me shot 10 was very concerning - I know myself, my gear and my load pretty well and instinct said - that wasn't some anomaly....but what to do (assess the test). It would have been very easy to discount shot 10 and focus on the little cluster and think I had a hammer and I muffed shot 10.
Your suggestion is in essence what I ended up doing (plotting vertical over time - if I understand you correctly) . I'm always interested in the process of how methodical, data driven shooters solve problems rather than jumping to a specific conclusion and trying this that and the other in a scatter gun maybe this will work approach or worse assigning it to some random variable such as pulling the trigger and conditions and then on the big day it all goes to custard because there is a fundamental that's not right.
