@tal I was considering placing "time reading" in my stories.
It is for average readers, to have an idea such as "so, it's long, let me read it later when I have more time, now I'm in the bus"...
But the number can vary. For example I read with voice synth, being blind; and I have a high voice rate. But when I use Braille to read, I might be slower, or faster, depends on what I read.
I'm curious to know which criterion has been used but IMHO every person should consider their timing.
