One of those "it's complicated" issues really and the simple answer is to wait and see what happens, don't try and prejudice it!
In principle, one of the criteria the system will pick up on is the proportion of scores at buffer for any given handicap level. Exact data to trigger a system recommendation is complicated but a 25 handicapper (for example) who plays 10 comps and is in his buffer every time would almost certainly trigger a recommendation for a reduction. A scr golfer with the same stats probably wouldn't!
