I got confused, not hard to do, with the rest of your post.
I have posted some findings from previous tests on this subject, which I think were not the results expected.
Anyway, found a batch of pellets last week that grouped superbly in REV26 barrel, sized to 4.52.
Also shot superb groups out of the tin, but about 10mm higher at 50m.
so I got the chrono down range at 50m, expecting the tin / higher impact pellets to be traveling faster.
They were not, both sized and and unzied were around the usuall "slower" speed of 560fps, with a fairy wide spread of fps, considering their grouping.
Thus, my findings on what has been an interesting idea is that a good pellet that groups, groups, no matter how fast it is going at 50m.
However, I have after the last 6 ish months of using a "go faster" batch with pass the 50m chrono at about 600 fps, come to the conclusion I am giving less wind on a light breeze day that I was with the slower pellets.
That, even I and Tattoo should have been able to work out, made sense faster = less wind.
Might try weighed pellets at 50m just to see what the Fps would be, sounds interesting.
However, having been down the weighing route before, I already know, if you have a good batch, weighing makes not difference to groups at 50m.
