2-7 TD the presence of a second hand

[NYplayer]

I just worked out in a speadsheet the chances of making a 7 by the river if you start with a 2-3-7. I came up with 20.61%. so basically if you take a 2,3 and 7 out of the deck and draw 3 doing your best to make 7 low that's how often you make it. then decided to check it against two dimes. I decided to do it by making my 2-3-7 have to beat a #5 (the best 8) that way i would be insured a 7. here is the result

to my surprise my equity is only 3.8%. this must be because the other hand has some of the cards i need no? so does this mean that when we are drawing against another player who is drawing 1 we are in worse shape than strict odds suggest? and if we're against 2 players drawing 1 we are in really bad shape? i though 2-3-7 was good [img]/images/graemlins/confused.gif[/img]
