I would imagine that the price went way down from $5 with it being a production run. We are talking 20,000 to 50,000 patches being run at a time. I would expect the cost per patch to have dropped to somewhere in the $1.75 to $2.50 range.
I have received no indications that this is the case. This is merely my experience in small and large production runs.
But yes, my interpretation of the interview was that 100% of the profits belonged to BIEI.
