Your Stableford score is irrelevant in a Bogey Comp - it’s a HC matchplay against a scratch player at the end of the day and then they use a formula once completed to work out HC changes
It’s all about winning holes against the course and managing your game appropriately for competition.
I don’t think they should use the term ‘stableford’ then as that is what is confusing everyone. I played with a 2 handicapper today, he finished +1, 1 bogey on 18 against 1 eagle plus 1 birdie on a shot hole.
