The results are in, and here's the dizzle. We each had 3 practice swings, then 11 that counted. The original counts were 5 / 11 for each of us - which impressed us both given the fact that neither of us had held a bat in about a decade.
Nobody in this thread guessed 5 / 11 for both of us, though, and upon further analysis of the video, Andrei skimmed the ball on one of his swings - putting him just barely over the edge at 6/11. Andrei wins by 1, and sky_lark - you take home the prize!
Video will be posted within the next hour or so...
