I think you/we/someone should hook it up to (or grab code from) ibam.
It already does this and also learns the correlation between charge
level and charge/discharge rate, which can make a big difference.  
It's available in testing & unstable.

  IBAM is an advanced battery monitor for laptops, which uses
  statistical and adaptive linear methods to provide accurate
  estimations of minutes of battery left or of the time needed 
  until full recharge.
