It looks like you have a very good understanding of the lifts! It seems like you have been doing your homework.
I'd say the third Snatch was the best one. But with all of them, the main issue I can identify is that you just need to be more aggressive with your extension. Keep the bar close and aggressively drive up with the legs.
I noticed, on the first one, that you were a little unstable in the bottom position. I recommend holding the bottom position of any Snatches/Snatch Balances/OHS for 2-3 seconds before standing so you can build that comfort level.
Also, it looks like you could keep your chest up a little more on that 1st pull. It's very slight, but when the weight gets heavier and heavier it could completely throw off the lift.
By the way, we appreciate your support! Greg probably wouldn't want you to get fired for not doing your job at work so I'm sure there's no hard feelings about the Performance Menu.
