Froome Back in Yellow!

Chris Froome got 25 s on Fabio Aru in today's Stage 14 and turned a 6-s deficit into a 19-s lead on the Italian cyclist.  Michael Matthews won what I consider to be a slow stage today.  Below is a comparison between the winning time and our prediction.

• Stage 14: 4h 21' 56" (actual), 4h 12' 56" (prediction), 09' 00" fast (-3.44% error)

We were too slow on hilly Stages 5 and 8, so power was upped slightly for today's stage.  We would have been under 1% without the change!  Oh well, that's what makes this so much fun.  We can't predict team strategies, crashes, and weather.  Below is our prediction for tomorrow's hilly stage.

• Stage 15:  4h 41' 26" (prediction)

I'm not tweaking the power in our model for tomorrow's stage.  Will I regret that with a rest day to follow???
