If you have a column for "Games Played" and "Games Won" then you could use these fields to display in tooltip right? Or are you wanting to display this in the viz?
Do you have the total number of games of each team??
if you have this information you can create a new calculated field 'num_win' :
[the percent of games won each season] * [total number of games]
([the percent of games won each season] * [total number of games] )/100
It depends on the percent of games won each season, for example, in your case :
[the percent of games won each season]= 0,8
and [total number of games]=5
then 'num_win'= 0,8*5
I am not sure you are looking for this but use below calculation to find desired output.
I have attached workbook for your reference. Please let me know if this is what you are looking for.
