I totally agree , but if say rate 2 turn ie 30 seconds the time available to accelerate this heavy mass is too short.
That is my experience, many times, especially in jetstream holding patterns.
So, a rate 2 turn gives a constant rate of change of heading. As stated in my examples above, it is still a velocity change of 200 knots over 30 seconds for both cases. Inertia is the same. Rate of change of direction relative to the air mass is exactly the same.
As for holding, I am not aware of what system you use in that aircraft. All aircraft I have flown for the last 20 years have FMS and fly a ground track - not constant angle of bank. This is why there are speed variations - variations in rate of turn to make good the ground track.
