The time makes sense if he's looking at the chart for literally every press of the key, like this:
*Looks at chart*
*Put finger on chart*
*Looks at panel*
*Puts finger on panel*
N
*Looks at chart*
*Put finger on chart*
*Looks at panel*
*Puts finger on panel*

*Looks at chart*

I'm using VR and almost have to do this exactly, but I can remember N 42 03, reference chart, 37, E, reference chart 053, 38, reference chart 26.
I don't know how he's coded, because I'm not privy to that information. But they've said it takes him time to find switches and and what not. Cool. That makes sense. But it sounds like the time it takes for him to initially find the panel is used for each key press, which ain't right. If you're holding your hand on the panel, it doesn't take 2 seconds to press the next button. I equate it to trying to type on your phone (like I'm doing now) and trying to type on a palm pilot with a stylus. All just my opinion, yes. But listening to a few examples I've heard, his typing is too slow.
