My complaint is that the warp factor only goes to infinity in the first chart you provided (the old system. i.e. as v –> ∞, fw –> ∞). They changed it from v = fw^3^*c. So warp 3 was 27c for TOS and ENT: https://memory-alpha.fandom.com/wiki/Warp_factor

Warp 10 being infinite is definitely cannon, just ask the haters what the worst episode of Star Trek Voyager is haha

(The headline of this wiki article is a little off, he doesn't travel "faster" than warp 10, he travels at warp 10)

Your second graph literally says "warp 10 is infinite velocity", which is the new system. That there are 10 energy thresholds is cool world-building, but basing your velocity scale on it is annoying and unintuitive. When they use these numbers, unless you crack open a calculator, you have no idea how fast it actually is.

In the new system as as v –> ∞, fw –> 10, and I find that annoying.
