More stats were added to the screenshot (not ratings):

Since these are STATS and not ratings, players may have results that do not reflect their skill level due to the opponents they play. But it never hurts to look at the stats anyways.

RL Drop % - Out of total # of RLs taken, this is the percentage of them that were dropped.

Kills per RL - For every RL that was acquired, this is the average number of frags

Lives to get RL - Average number of times you had to die before you finally got an RL

Time per RL (s) - Average number of seconds you had RL for each RL taken

Time to get RL (s)- Once you died, this is the average number of seconds before you got another RL

% time with RL - Per game, this is the average time you had an RL

RL vs RL win % - Out of all battles where you have RL and so does enemy, this is the win percentage

RL vs X win % - Out of all battles where you have RL and enemy does not, this is the win percentage

X vs RL win % - Out of all battles where you do not have RL and enemy does, this is the win percentage

X vs X win % - Out of all battles where you do not have RL and neither does enemy, this is the win percentage
