I recently proposed a trade with a member whom the swap list filter said ‘Coins That May Interest Him/Her’ of 500+ of my swap items:

and he responded that I had nothing of interest. Nothing out of 503 seemed a bit unlikely even granting the passage of time and changing interests, etc - so we had a short exchange about it.
It was my understanding (from the text below) that that 503 number was based on the intersection of his Wish List and my Swap List:
But…..he said he has no coins at all marked as Wished, and that a full Catalog Search for him filtering on ‘wished’ returns zero items.
So now I'm just very confused - if he has zero wishes, how do I have 503 coins that may be of interest to him based on his wishes?
What IS that number based on?
