Yes, the 0.275 is the pump reset value and you then make fine adjustments to the eccentric roller whilst performing the test on VIDA or Vol-Fcr .
The 0.55 value applies if you don't have the software to hand to perform the dynamic timing test and using just a dial gauge.
Assuming the camshaft is correctly aligned and locked, fit the pump belt and tensioners with the pump cam pully screw slightly slackened to allow the pully to turn. You can now set and lock the pump at 0.55 with the dial gauge then, using a suitable counter hold, torque the pump cam pulley screw.
Don't forget to undo the pump locking screw and replace its shim!
