"Win %" includes 50 extra wins and losses for all cards.
Known as
Laplace smoothing, this
puts more weight on cards with more plays.
Multiple copies of a card count multiple times.
For example, a 7-3 deck with 2 Shadow Assassins would count as 14 wins and 6
losses.
Card wins and losses are per-game, not per-run.
A 7-0 deck that swapped out Shadowshift after game 4 would count as 4 wins and 0
losses.
Some uploaded runs are incomplete. We add an extra loss for any incomplete 0 to 5-win
deck.
For incomplete 6-wins decks, we add half a loss and half a win.
