Did you use Edge to Push The Limit, Irn0rchid, and if so, shouldn't you be rolling 7 dice (Charisma 3 + Edge 4)?
If not, you need to use 6d6 T 5, not H. Didn't matter in this case because no sixes were rolled, just a heads up.
From the dice roller help:
tZ - target number Z, count rolls that meet or exceed Z as successes (if Z > Y, implicit oY)
hZ - hits Z, count rolls that meet or exceed Z as successes, max roll grants bonus roll (implicit oY) (WoD)
Example:
20d6h5: 5 [20d6h5=4, 1, 1, 2, 2, 1, 4, 3, 2, 4, [6, 6, 4], 1, 3, 1, 5, 5, 3, 4, 3, [6, 2]]
