Pitches on mouthpiece

[BatteySax]

I'm just wondering, what the pitch on an alto mouthpiece (say mine, Eugene 4r) would be if you were exerting perfect air pressure and embouchure? This would greatly help me out, and also, if there is a note on a YAS-82Z that I can tune to and have low D ( :space0: ) and high D ( :line4: ) sharpness/flatness minimalized. Also, I'm going into marching season, could use a few tips on good rental saxes because I'm also going to be using it for jazz band and the such.

Any help would be great :)

Concert A for alto mouthpieces, according to the late Santy Runyon who apparently come up with this mouthpiece exercise.
