I don't worry about chainline, if the chain stays on and is relatively quiet, I am happy. Granted I have generally just gone with manufacturer recommendations or the closest thing to that or just go with a Hollowtech II style crank and not worry 'bout it.

I guess the Sealed 75 BB is a bit longer for bikes that aren't pure track bikes.
