New Brehm label info

I see Peter Brehm is now offering YAN and MAL information on his labels. I
know what YAN is, but what's MAL? What is a "good" level for both these
things? Is there an easy way to determine how much DAP is required to bump
up YAN to the desired level?

I know I could probably look all this up somewhere, it's just easier to ask.
;-)

Thanks
