Sugino XD600 crank BB?
 
Quick question(s) since I know this crank is relatively popular

If you have an XD-600 and a 113mm BB, is the DS 3mm farther from the chainstay than the NDS?
If you have an XD-600 and a 110mm BB, is the NDS 3mm farther from the chainstay than the DS?
If you have an XD-600 and a 107mm BB, is the DS 3mm farther from the chainstay than the NDS?

I saw that Sugino specs a 110mm BB for 45mm chainline, and I'm wondering if the +3mm on the NDS compared to the 107mm results in a symmetrical crank spacing since the 107mm and 110mm would both have the same chainline.

Got Sugino XD-300 cranks with RPM 7420 bottom bracket (115mm). I believe the difference between XD 300 and XD 600 was inclusion of steel vs. aluminum chain-rings. My measurements show crank-arms are nearly the same distance from the chainstay on both sides, about 15mm, with the NDS slightly further away.
