A bit fast on Stage 19 ...

I thought someone could finish Stage 19 in just under three hours.  I was wrong about that!  Here is the result from Stage 19:

• Stage 19:  3h 13' 25" (actual), 2h 57' 54" (prediction), -15' 31" fast (-8.02% error)

Pierre Rolland had a great climb at the end to overtake Alberto Contador.  Here is Rolland's average speed:

• Stage 19:  9.44 m/s (21.1 mph)

I'm always glad to be under 10% on my predictions.  Even though I was 8% off today, I thought the stage could have been done a little faster.  Here is my prediction for tomorrow's individual time trial:

• Stage 20:  51' 06" (prediction)

Can the Schleck brothers be stopped?
