Your link shows that yesterday had the highest peak demand of the month and it was between 1-2pm.

Spot checking July 2019 the oldest year it had, it's peak day also had the peak at the same time.

Do we have different definitions of "late afternoon"?

I also don't understand the link's differentiation between "demand" and "usage", but "demand" is higher and nearer noon it seems.

It's also not clear if home solar is accounted for and is a factor. You'll see a "demand dip" when behind the meter solar is generating if you're only seeing the grid side of things. Some grids estimate and include it or call it out separately.
