Autorate rule for headsup game to pokertracker?

I am trying to find somekind autorate rate rule for headsup playing.

It would be great if there is any good ones. Even better is someone is willing to share it [img]/images/graemlins/wink.gif[/img].

Maybe I am dumb, but did not find any of those. Have not read any book about that subject either, but if there is some good books, then propably making somekind of autorate rules based to that book might give some direction.

Well, IMO it would be pointless to make a PT autorate rule for heads up play because so much of your own play is based off of the play of your opponent. If an opponent saw every flop and raised 90% of the time you could not classify him has a maniac because that style of play might be best against you. See what I mean? An icon would only help in an overall general sense where you could say this player is aggressive or this player is passive. Just my $.02
