Whether it will make any difference, I don't know. Making yourself taste nasty doesn't do any good after the sharks have ripped you apart. But you should note your scores and ask for a proper handicap (only three scores are required).
I have managed to sort out my golf swing to the extent that, this year, I will be like that recurrent character in films and stories, who is beaten down by circumstances and malefactors of various kinds, and finally rises up above them all, for glorious victory after glorious victory. This is only possible because my multiple dreadful humiliations of last year gifted me a handicap of 24.7.
That's the great thing about the new World Handicap System - your handicap can go up or down quite dramatically.
If you play proper rubbish for a while you become very competitive again.
Not sure about these home-made handicaps though..
