I'm still new to poker but the way I work out odds and how Dan Harrington seems to do it in his books is by calculating the unseen cards left.

Therefore even with 6 players left it doesn't alter the fact that after the flop you have 47 unseen cards left, after the turn 46, and on the river 45.


Flush Draw:

Flop (47) 9 outs (5.2:1)
Turn (46) 9 outs (5.1:1)

So to make the call you would have to be getting better pot odds than those on the particular street you're on.
