Also, strategy-wise, this means you want to trade with the tightwads like HC before you trade with Mansa.
That's the obvious implication. For example, if you trade with Mansa first, you will have passed everyone else's WFYBTA limit before you trade with them. But if you trade all the others up to their limit and THEN go to Mansa, he'll still trade (assuming all other conditions for trading are met).
