Two off the midpoint seems to result in the least wastage. I doubt there's much difference between the various plays.

i was going to suggest to roman we played out the race online, with me deciding the herd's moves.
i then looked at this roll again and then at the gnu hints -- i was very surprised by its order of choice and though the figures quoted for equity and difference are small -- they often are for other moves too.
this made me decide to keep the polls going, and i will be very interested in your comments.
i will post the order and equities once the poll is closed

7-2, 7-1 spreads 'em out and unstacks the bloated bar point. But, as ah-clem says, there's lttle difference between the various plays.

the order is actually the opposite of the poll choices!
