(Slowly) Picking a brand new PACKLOCK 90A-PRO lock with amateur commentary

Here I'm trying to talk through the thought process I use to pick a very hard lock for the first time. Unfortunately the the core and pins on these locks are so aggressive that the feedback you get from them is quite confusing and obscured so my commentary isn't entirely precise.
Note that I made a mistake when examining the key. I skipped pin 1 which is actually a higher cut than I was expecting. Pins 2, 3, and 4 were super-low cuts. 5 and 6 were high, 7 was medium.

It’s the first time for me to see a video of lock picking. It’s eye opening.
