Hi BE-proff,

My answer is: 'Educated Guess'
No one will decide which GMR you should use behind your back.
Fully ACK the ElMaestro's answer below.
I'd cite another Master's post:

If you intend the next study to be pivotal then the choice of GMR guess should reflect a ton of factors including biology, dissolution, gut feeling, Saturn's moons, your biorhythms, personal horoscope (you've gotta ask yourself one question: "Do I feel lucky?" Well, do ya, punk?) etc but not your management's desire to save money.

Please also think about GMR = 1.19
Would you recommend to use the formulation with REAL GMR = 1.19 in practice?

Kind regards,
