Yes #1. I've had the same experience with workshops/seminars. I went to a seminar about intellectual property rights, and it was exactly this kind of mixed bag, some useful info, some useless time wasters. One of the speakers was a VP of one of these social media giants, who used her talk to give us a product demo. "Here's what you can use this for!" "Here's how you use this feature!" I kept waiting for her to say something about copyright but she never did. Honestly, one of the things I had most wanted to hear was a senior executive from a social media giant talk about copyright infringement.
Yes #2. If I was going to test image stabilization, I don't see flash in my methodology. In your case I think the word may be "conflate"?

I very rarely ever go to photo "workshops," but took a chance and went to one tonight covering iTTL flash and portrait posing. There was a pretty knowledgeable guy giving the demonstrations, a couple of Tamron guys there with a table full of lenses, and "Interfit" gear prominently displayed all over the place. About one third of it was name dropping of famous clients and funny stories, another third was info that was actually useful to me, and the other third was basically a TV infomercial for Tamron, Interfit, and Nissin. I don't know, I was getting kind of irritated with the barrage of how great the (featured brands) were.
At one point the guy turned off the lights in the room and there was only a small modeling light at low power on the model, to provide focus. He then said something like, "I'm going to turn shutter speed all the way down to 1/5s to show you how great this Tamron 70-200mm VC is! He then took a shot and the speedlights all popped. Shot came up on the monitor a few seconds later, and he said, "See just how sharp the Tamron lens is even at 1/5s? The VC on this lens gives you at least five stops! The crowd ooo'd and ahhh'd. I was sitting in the front row, and while I know I'm nowhere near his level, I do have a very solid fundamental understanding of flash. I asked, "BUT, there was no ambient light here. ALL the light came from the flash, so the shutter speed really didn't matter at all since the flash duration only lasted something like 1/1000s. In other words, the flash duration became the de facto shutter speed. You could have turned the VC off and the shot would be just as sharp." Well, there was an uncomfortable silence, and then he said something like, "There was a little ambient light coming from the model light." --about 8 stops less! The strobes completely crushed it! I did learn a few useful things but I'm really not eager to go to another one of these. I'm sure there will be times I won't be able to spot the BS. I'd rather just pay a local guy some cash to learn a few things without him trying to sell me anything.
