So the VNAV will start with 1000ft/min if below the optimal profile. If it reaches the optimal profile point on the flight path it should have switched to a new V/S value that would have brought me to FL 110 exactly over GIVME, correct?

I.e. when 2000 feet too high and GS showing 384 kt, if already descending on idle thrust and the resulting V/S is 1400 fpm:
a) the aircraft is deviating further above the profile
b) the aircraft is flying parallel to the profile
c) the aircraft is flying steeper than the profile angle, and wild eventually intercept it from above.
You know the answer.

EDIT: out of interest, what IAS would you normally fly in such an exercise?
Answer should be a)
But I'm not sure about the right IAS.
