The only thing that seems weird is I never feel like I did enough during training and tests, though, all the dive masters and instructors say I am a very good diver. Don't want to let that get into my head, I'd rather be a cautious diver then think I'm good and get cocky.
You know I've always felt the same. The couple dives you do for each specialty really isn't enough I think. I don't even think 4 for OW is enough either but I persisted and kept at it and found my way. When I took the drysuit course it took me 8 dives to really get comfortable diving in it which is 4 times as many as the course required. Repetition is key and skills should constantly be performed.
