Decipher flow chart?

Happy 4th of July boys!

Looking for a bit of help deciphering this flow chart I have for my D1AE-GA 351C heads. This port/polish/flow work was done by Air Flow Research in 1982 for my father and the heads have come into my possession and I'm running them now. I've always wondered what these figures mean because I've never seen a flow chart like it. Hand written on it says 400cfm on intake side and 300 on exhaust side. I would assume that was measured at the given max lifts on the chart? .700 and .600 respectively? If that's so, then what do all these other numbers at different lifts represent?

I figured it would be work wise to understand this chart for when the day comes I want a custom grind cam! Hope somebody out there knows what we're looking at!
