yet another handicap question

how does playing in compertitions with max handicaps affect your real handicap.

Just hyperthetical but say if your handicap is 24 and you play in a normal max allowence comp and you win with 38 points you should get cut.

But what about if you play in a max 18 comp would you still have to score 37 points to get cut or since you have already have been dropped 6 shots for the compertition would somewhere around 31 points meen that your handicap is adjusted?

Hope you get what im asking as i dont think i put it across right

Handicap adjustments are always off full handicaps regardless of the playing handicap in a given competition
