Why is this?

[cavalier]

I set up the following situation at http://www.twodimes.net/ using pokenum hand analyzer.

It's 4 player 7 Stud hi/low 8 or better

Player A [Ac 4c] 2h
Player B [Ah 4h] 2c
Player C folded As
Player D folded Ad

So, aces are dead and the hands are tied.

The results are here.

Running: pokenum -mc 500000 -7s8 ah 2c 4h - ac 2h 4c / as ad :
7-card Stud Hi/Low 8-or-better: 500000 sampled outcomes

-----

I ran the simulation several times, same results.

Notice the edge by player B.

I'm assuming the results are approaching 50% each, but haven't gotten there because of an insufficient sample size?

Thanks
