EV Exploration: Bets Below 1 ETH

I've run EV studies for bets under 1 ETH at $0.50, $1.00, $1.50, and $2.00 transaction cost points. Green is above 0 EV, red is below 0 EV. See links below:

$0.50: http://i.imgur.com/tgsvHPw.jpg

Of note is the particular sensitivity of the average bet (let's say .5 ETH) to immediate degradation of EV. At the modest transaction cost of $1.00, EV at .5 ETH transforms from .01 to .0062-.0063; essentially 63% efficiency.

Edit: For easier viewing, in Chrome or Firefox I would recommend clicking link, zooming in, then Control minus to view. TBH much easier to see on Ipad.
