Chainline for Ultegra double?

What is the chainline measurement (for the front chainrings) for a 9 speed
130mm dropout spacing Ultegra double drivetrain? How much deviation from
that is reasonable?

Thanks much

Also, for many years the Shimano book has specified 43.5mm +/-1.5mm
for all double chain rings, except Dura-Ace, which is +/-1.1mm.
