It’s not average - the legend implies the largest size DD is in the dark blue, the smallest A is in the lightest blue.
Basically an A cup in light blue could be 10cm and a DD cup in dark blue would be 25cm or something.
It’s not clear in the slightest.

that is probably because for some reason, in america, people think of DD as being enormous, when in reality american bra sizing just sucks and places seldom stock larger than that.
