It is unfair to the side batting first, because it only takes into account the completed overs and then extrapolates that run rate to the remainder of the overs, however most teams bat at substantially higher run rate in the last three-four overs then the previous overs.

Actually D/L does not extrapolate the current run-rate to the remainder of the overs, it also considers wickets in hands and past match results including the fact that team bat faster in last few overs. However, the team batting second will still get a huge advantage as having 10 wickets for fewer overs is always much more advantageous
