Absolutely
That's unusual, but it is something I've used after taking GUE fundies
I only started teaching in 2015 and in my area, pool time was very expensive. I cannot speak about how it was in the past.
However, there is no defined time for courses. There are minimums for open water dives in terms of time, depth (well, minimum and maximum), and number. But it is all dependent on the student (how quickly they pick things up/master) and the instructor (how good are they at getting the material/skills across).
What is it you are actually looking for? Now what many of us have discovered is that it takes less time to teach neutrally buoyant and trimmed. The front loading of getting students neutrally buoyant and trimmed pays off big time as the other skills go more smoothly. Remember having a student spend their time waiting to perform a skill to be floating in the water column is far more beneficial than sitting on their knees.
So while you didn't ask for recommendations, the number 1 criteria is does the instructor teach the entire course, confined water included, fully neutrally buoyant and trimmed. You might be interested in my 3-part blog series on the SDI log.
The quality of courses varies dramatically, which you already know. I would hope that you are seeking solid training and are meaning to ask what amount of pool time should a good class have. Is this correct?
