Shamano's spec cannot be right. Just looking at the picture it's obvious that the mid point between the flanges is not the same as the centre of the hub (half the OLD).
Measure from the face of the left over lock nut to the mid-thickness of the left flange.
Half the OLD (50mm) minus (1.) gives you the CTFl
Measure from the face of the right over lock nut to the mid-thickness of the right flange.
Half the OLD (50mm) minus (3.) gives you the CTFr
If you find it awkward measuring, drop the hub vertically into a hole up to the face of the over lock nut and rest a vertical of some sort up against the flange to measure it.
Trust your eyes, not someone else's typing!
