I'm not sure how it comes up with the number. My #1 match says our match score is 268 yet I looked and it shows over 400 cards for each of us. Even discounting the duplicates I don't think it's more than 150 dupes.
Be that as it may, it shows 2 people over 100 trade score and 266 people total. I was so busy looking through the trade matches that I forgot how many hit 10.
VERY slow trading due to health problems. Not transferrable so safe to trade with, just moving is painful and can't always access the cards.
