I guess my posts did end up a bit technical and hard to read - sorry
In short - if you put out a chrono at 50m and you notice no change in fps (either average fps or spread) with or without the stripper then as far as I know there's no ballistic theory to back up the claim that it will take less wind.
(That doesn't mean it can't happen, It could mean that theory hasn't caught up with air gun slug ballistics - or it could mean you're imaging it)
What I found with my test of two pellet batches was that there was an increase in fps and a reduction in spread. The difference that made to the vertical impact point wasn't noticeable, but there is theory to support that the difference in wind allowance could be quite noticeable.
