I don't know . . .
So on a typical 11 hour week on the hard ride I'd go like Z1:31', Z2: 1:22, Z3: 38', Z4: 1:01, Z5: 8', everything else zone 1 or 2. Or Z!: 17', Z2: 1:24, Z3: 39', Z4: 1:15, Z5: 11'. Something on that order though I don't think I ever went over 1:30 in Z4 on any long ride. Of course I was an old man and maybe your time in the upper zones would be a much larger percentage of the total.
Those are HR results. After I started using power in '19, on a 10 hour ride results were about the same, except that Z4 was smaller and Z5 larger, the total being about the same total (not percentage) I'd get on a shorter ride, about what one would expect.
