Should we plan our release date or not?

I see two schools of thought out there regarding whether the chasted male should or shouldn’t know when he will be released for orgasm. It seems like it is generally a given that the release date is set and the chasted male knows it exactly. However, I just ran across Gorgia Ivey Green’s opinion that the chasted male should never EVER be told when the release date is. That seems to make a lot of sense to me, and now I’m wondering why I haven’t seen that opinion far more frequently. If the chaste male didn’t know when he was going to be released, wouldn’t it inspire him to be in top form all the time in order to provoke a surprise release? Otherwise, if the release is known to be 2 weeks away, then one might just be inspired to “keep under the radar” and wait it out. If I were the keyholder, I think I would get a lot more out of my slave if he didn’t know the release date. What do you think?
