Thanks - That would certainly explain the behavior.
Yeah, if they changed it to take the cut after fees and taxes were deducted that would be a reasonable solution. It seems more in line with the spirit of the give 100% idea, versus "owing" itch more and more each time revenue is shared with them.
While it may be by design, the current approach does seem "bug-like" in that it could create very small accounting nuisances over time. If they can take 100% of the funds before taxes/fees are paid, and yet they are also still paying those taxes/fees then they're just going to accrue something like "accounts receivable" that will never get paid (at least I'm not inclined to pay additional fees in order to compensate for that).
