very simple question, I'm trying to learn advanced principles of .net and c# and I'm in the middle of creating some simple manager game. Now I should implement some experience for players.

I was thinking to implement some kind of enumerated values like this

private enum ExperienceValues
    { 
        FriendlyMatch = 0.1, 
        Training = 0.15, 
        LeagueMatch = 0.6, 
        CupMatch = 0.85, 
        Qualification = 1.4      
    }

And to calculate experience by the time user spend on the field

90min * 0.6 = 54

Is this approach ok ? How can I abstract experience calculation for common sports (team sport). Thanks
