I think about men basketball where in 15/18 editions the gold medal is taken by team USA.

Is this 83% (=15/18) the higher percentage for a single olympic events gold medal won by the same Country?

I would like to consider both summer and winter editions but only speciality that were present in leat 10 editions

I would like to consider both summer and winter editions but only specialities that were present in at least 10 editions.
