Instant Ink - replace cartridge? Or don't?

[M0ntyD0g]

Hi - I'm subscribed to Instant Ink. I've just received a replacement black cartridge. The accompanying email says that I must replace as soon as possible. But why?? Settings says that my existing cartridge is more than three quarters full, and the label on the cartridge says I should wait until it's empty before replacing. So should I replace or not?? Confused....
