The way you’ve added it puts more emphasis on the 200m, and more emphasis again on the 400m.
To compare fairly, 4x100m + 2x200m + 400m is a better representation.
They get totals of
Bolt 121.98
MJ 122.18
Gay 122.81
Very close between Bolt/MJ, and Gay not that far back on average over 1200m total distance (5/100th per 100m).
