As to your specific concerns with the timing:
I checked my watch when entering the security line, it was 9:30 am, a little over an hour later I was re-directed to the kiosk from the normal GS line by a CM with a tablet. Starting to think I should've refused. I had already texted DH, back at home to share re the long wait. Going by my text time, and fact we were getting 'close' estimated the total of that portion of wait.
OT - my DS, in his early 20's, was pulled every single time we entered a park for extra security, which never took more than a few minutes. He had no issue with it, nor did I, but we assume he fit a profile or just looks shifty.
The 2nd line took longer, probably not that much more than the first, but it 'felt' much longer at that point. when I finally was face to face with CM @ the kiosk, checked time again to relay it to DH. That's how I knew that portion of GS wait took 30 minutes.
Didn't take long to go thru turnstyle, no more than 10 minutes. Walked into park a little before noon and headed back for BoG ADR.
Since you are paying close attention & following my time line very carefully, I'll let you do the math as to estimating the over-all time I spent in the GS line lol.
