The Print Time left value improves in accuracy but is pointless in precision.
Approx. Total Print Time: 3 hours
Print Time: 02:08:51
Print Time Left: 1 hour
It's said "1 hour" for half hour and based on the precision of the output that's about mathematically correct.
Can it not be more precise like saying, "1:12 remaining" or "0:47 remaining"?
