Toptracer 9 shot challenge | Golf Monthly

Did this morph into the Approach Challenge?

I had I think 4 goes at Pebble Beach yesterday, 3 in the 4 hundreds range, one crept into 5 hundred. After first attempt I was trying to keep down to 3 hundred and something but failed.

There were some stupid low scores on the leaderboard, but I was thinking what would be a "strokes gained/lost" comparison for a 9 handicap - does anyone know?
