GPS sensitivity

The latest release notes indicate that the GPS sensitivity has been decreases, to increase battery life. Does this mean that the app will assume that you are following the calculated route, until it accumulates evidence to the contrary? I have had a lot of problems with this app failing to give voice directions until it is CERTAIN that I am on the road I should be on, or recalculating when I have not made a misstep. I greatly hope that these issues have been fixed already.
