YT, I think I twigged before typing the words that nobody will happily hand over their best score of the season, and I agree with you that it would be particularly off-putting for a new shooter. I'm down to A grade locally and I would hate losing my best score if keeping it meant I would be re-promoted.
But it would of course be the same for everybody, and there's no denying that from a stats point of view it's the correct thing to do, even if this year's figures don't demonstrate a benefit.
It probably isn't the cause of the present concerns; it just seems to me that if any changes are to be made they should be all-encompassing and be not only acceptable but demonstrably logical.
Good debate anyway.
