Was just about to ask the refresh time, I specifically chose this one due to it's faster refresh time (1 s) compared to color displays: https://shop.pimoroni.com/products/inky-what?variant=2121402...

You pretty much do two full refreshes, and then some. The first one drives the pigment (red,yellow) layers, and then the black ones.
