The Winning Percentage (Average Outcome)
is calculated as follows: each Narrow Win counts as 60%, Clear Win 70%,
Decisive Win 80%, Win by TKO 85%, Win by KO 95%. The total for each fight is then divided by the number of reviews.
Then the grand total is further divided by the number of fights.

Winning Percentage is therefore different from the Win-Loss record which is immediately above it in the
table. For example, a player can have a winning Win-Loss record (5-4-2) and a losing Winning Percentage (48%) at
the same time if most of his wins are narrow while most of his losses are heavy.
