Kinda ironic that they talk about the legibility of the numbers but the page they are presented in is quite hard to read: https://i.imgur.com/DItuHiL.png
May be they should just stick a static HTML page? No javascript should be necessary for displaying type, am I wrong? Why do we need animations? Why do we need this presentation hoohaa?
I thought that the point was to show that even in a challenging setup like that one you can still read ok
