Looking for work as Dota 2 panelist / statistician / analyst in broadcast 
Explain this to me
This section contains stats for most common hero pairs. Winrate difference is calculated based on average expected win rate of the heroes together. Expected matches is calculated number of matches the heroes would be picked together randomly based on their pick rates. Deviation is difference between expected number of matches and the actual number (higher number is better and means the heroes are usually picked together intentionally, negative values mean otherwise). Percentage is how much of actual matches is the deviation number. Minimum amount of matches for pairs is set to 6.
