You know what, let's just go with sawdust and planks....
I don't think that would be accurate. If you look at all her posts, she is very critical of herself and her diving. As I think any new diver should be as we have a lot to learn and not being honest with yourself could lead to injury or worse. So the sawdust and planks isn't very accurate.
From my perspective, she saw her first OW class that did not involve her LDS and she saw big differences in how they were being trained and how she was trained. She posted about it here where we all post about experiences and comment on them.
It was a very general observation and one that has led to some great discussions on danglies (I can't type that without laughing) and training.
What I took away from the OP is she was shocked to see that and by posting it here she was looking to see if others had seen new divers in a class looking like they had no idea what they were doing. Pretty benign IMO but we all see things differently which is why I love posting here.
