which is actually the point. you can't figure it out, with your human brain 
that excels at fuzzy thinking, and you expect a computer to?

you're asking for magic to happen. "please predict how many phone calls i'll 
get in the next 2 hours" <-- that's what it would take to translate "one bar" 
into "38 minutes left"

i think most people tend to just look at it and go "hm. i have 25%. i don't 
need to worry just yet."
