Your video sounded a tad fast at 2x and pretty fine at 1.5.
Now I think speed adjustment come less from the natural speaking pace of the person than the subject matter.
I'm thinking of a channel like Accented Cinema (https://youtu.be/hfruMPONaYg), with a slowish talking pace, but as there's all the visual part going on at all times, it actually doesn't feel slow to my ear.
I felt the same for videos explaining concept I have no familiarity with, so I see as how fast the brain can process the info, less than the talking speed per se.
