I doubt that a stableford comp will happen, As we are all deemed to be scratch golfers (no handicap system in place) the only advantage would be for the odd multiple blowouts we have. For stableford scoring to work there would have to be handicap system in place - and that will not happen.
The amount of programming changes and time would far outway the benefit.
I suppose you could try it on a small scale within a CC Comp, but would require either screen shots of the score cards (or played as a challenge) so you could then assign the points from the scorecards, or as a M/P stroke round between 4 people. Too much work for little reward in my opinion.
