I think the worst ever was in a "practice" round (single in the afternoon and 4-somes ahead with nobody behind) where I put about 8 into different "lost" situations. To be fair, I had my "game" ball in play and then would try the "hero" shots (get after the pin 3 yards on over the lake) and the "fitted" shots (back when I could draw and fade the ball with control). Most were lost in the "hero" category (big surprise) when trying to overhit short/mid irons into absurd pins and a couple were fitted shots that were overcooked a bit.
... ok they were duck hooks and "power fades". LOL!
