Discrepancies between trading opportunities and profile page

It looks like there's a difference between the value that I see in the trading opportunities page and what I see when viewing a user's profile (and it seems more than just the issue with foil vs non-foil pricing).

When I see user Avon in the trading opportunities page it says he has $3.02 in value that I need, but when I view his profile it says he has $8.08 that I need (and eyeballing it, the latter looks much closer). I see similar discrepancies with many others as well.

Also, it would also be awesome if we could see the NUMBER of cards, and not just the value, in the trading opportunties window -- just like we do in the marketplace, so I can know if someone wants $200 worth of cards, or really just wants 1 $200 dual-land.
