I have a couple of thoughts on the process, which I think may be useful for the discussion. For context,
@Manatee Diver and I are training siblings - I did the bulk of my training to date with Reggie, but began working with Chris in September on days that Reggie wasn't well enough to dive.
1. New Buddy Relationship
I always thought of Reggie and me as a buddy pair, even if we were a student-instructor pair. We had about fifteen dives together and we were getting better at observing one another, communicating, anticipating each other's movements, and perhaps even a bit of mind-reading. I feel that good buddy connection is critical in a high-stakes environment like a cave, especially when one buddy is a learner. We're still learning Chris and Chris is still learning us - this will take some time, but that's expected.
2. Different Teaching Style
Chris is one of Reggie's most accomplished students and mentees. When I work with Chris, I can still hear and feel Reggie's training coming through -- but Chris was also a teacher for many years and has a distinct pedagogical style. Reggie and Chris take different approaches to complexity.
Reggie liked to introduce problems one at a time and see the student respond correctly several times, with increasing mastery. Once Reggie felt confident that the base skill was solid,
then he would integrate it into a simulated cascade failure. Without knowing Reggie's exact stance on the matter, I would chalk this up to one or both things:
(a) Reggie cared very deeply about each dive being a safe experience and did not want to have someone biting off more than they could chew and creating extra risk;
(b) Reggie seemed to prefer evaluating skills separately (i.e., I was a Basic Lost-Line Drill Diver and a post-Apprentice Blackout Air Share Diver for a while), which were part of the whole picture. Once a student succeeded at all individual skills and with the proper level of mastery, he'd certify for the next level.
My experience with Chris is much more brief (one day of training at Ginnie, one day of fun diving at Madison Blue). However, my early impression is that Chris values a holistic approach where demonstrating skills in novel circumstances and combinations shows mastery, rather than iterative improvement. During our training day, Chris "killed" me (or attempted to kill me) with navigational/other mistakes that would need to be handled correctly, without prior discussion. These moments were super-instructive for me in understanding where I had gaps in my skills and awareness.
Reggie's approach helps to build a solid foundation of puzzle pieces so that you know what to put together; Chris's approach focuses on getting the puzzle assembled, even if you don't know what the puzzle will look like when it's done.
I think that both approaches have a place in a training progression.
3. Leveling Up
As an almost-too-obvious-to-mention issue,
@Manatee Diver and I are both leveling up from Basic to Apprentice content. We're performing more complex tasks in more challenging conditions and need to demonstrate a higher level of mastery.
Speaking for myself, I find that roughly every other day feels significantly harder than the day before. I think what's
really happening is that the previous day went well, the next day involves harder content, and now I'm actively working to close a skill gap towards the next level of mastery.
