Did you just count those which had 'mild' in the name? I seem to increasingly come across dark brews, sometimes claiming to be porters but often just with a silly name, which I would categorise as milds. And that's not even thinking about what we used to call light milds (are there any left?). I know some brewers decided to stop using the term - presumably under advice from brand-mongers - like McMullens, which you do call AK Mild but they don't any more!
