A SAGE mistake / sng's

[jool]

Does sngwiz/sngpt automatically assume 50/30/20 payout? If not couldn't you set a 100/0 payout, put one opponent, and have a much better tool than SAGE?

If not, how hard would it be for someone familiar w/ icm to make a program that adjusts to the 100/0 payout of a headsup sng? I feel like I must be missing something, cuz why didn't someone else notice, but can't think of what it is.
