I believe I based the ratings (and I can't remember which was good, positive or negative, but I am going to assume a positive rating was good for me) thing on what one person was likely to leave at or take from the table, adjusting accordingly if they somehow singularly affected my play (Tina for instance, who is about a +3 or +4, but since she is playing with my money tends to affect me as if she were a -10). I'd say Daylan is a pretty square +10, because he usually loses fifteen to twenty, but occasionally gets lucky. He actually played quite solid poker one night when it was me and him head to head, but he still would have lost to me, if he hadn't had four of a kind to my full boat, twice. I ended up winning a dollar or two. He raises pre-flop on aces, and sometimes that is correct, and sometimes it is stupid. Of course, it is correct a huge percentage more of the time the less people there are playing, so I guess in head to head game his pre flop shenanigans are not so bad. A couple of night after that, though, I saw him raise pre-flop and then fold after AKQ flopped. One has to assume that either he was holding a pocket pair and correctly folded them, which he is not likely to do, or he was just raising on crap.
By the way, the only reason I called his all-in bet was because he said "I am going to go all-in in two hands," and then did. If you'd been kind enough to tell me you were holding ace-king I would have gladly let you go it alone.
