I think a team of four low single figure guys won a texas scramble last year with 16 birdies, an eagle and a par (gross). Skooted the comp.
I once played in a comp where the winners had 16 birdies. All low single figure golfers, annoyingly all nice blokes as well. They won a few comps that year but that was their best effort. You can't argue with that level of golf. Can't beat your one though.
