but our calculation will still be wrong. and that's a cardinal rule: the user 
is allowed to get it wrong. the computer can't without diminishing trust in 
the system. lower trust translates to lower enjoyment and less value placed in 
the system.

it's not about us looking better, it's about allowing the user trust the 

is there really 30 minutes of battery left? no.
is it really 15% charged? yes.

which one leads the user to trust that the system offers correct information 
and can therefore be trusted and even pay a bit less attention / be less 
mentally concerned about it?

all the user will care about the 30 minutes is that they eventually learn it 
isn't really accurate and so they can't really trust the system.
