Diaper Changing With an Engineer

A perfect diaper change takes at least five minutes, and there's an 80% chance the diaper will leak anyway within an hour.

A half-assed diaper change takes 60 seconds, and it's nearly certain that the diaper will leak.

What's four minutes worth? Does it justify striving for that 20% chance of avoiding laundry?

24 hours in a day * 80% = 19.2 soiled outfits.

24 - 19.2 = 4.8 outfits saved.

4/60 minutes = 0.06667 = 6.67% of my time.

I'm going to have to wash something eventually, anyway. What's the difference?
