Are you saying that there's more than 4 significant digits in the 'best' answer?

Me too, because I'm not sure in which way you find flaw.
The statement I use is "Just because your calculator shows 8 digits doesn't mean they are all important".
On the other hand, it is very important to know just how many digits you
really have to work with, and a good idea of physical reality to check for reasonableness.
