I had my gps strapped to the tail logging at 5Hz when I lost the brakes and ran into the tire wall outside of T6.
First, here's that session's data displayed in Google Earth.
Now, here's a graph of my speed for the last lap and a half:
So, the Y axis shows speed in MPH while the X axis is time. (The label is incorrect, it looks like the units are seconds).
So the first peak on the left is my brake point for T1, the next peak is the brake point for T3 while the next one is for the bowl. The following peaks are T9 and T11, followed by another run down the front stretch.
Comparing the third peak, my last successful pass through the bowl with the last peak, my not so successful rapid stop out the bowl, I notice a few interesting details.
That little spike that appears after the last peak is probably from the tail accelerating past the nose as the bike flips over having hit the tires.
The slope of the last peak isn't as steep as from the previous pass, indicating that some brake power was available, but not as much as usual. This agrees with the marks on the one recovered pad, that seems to indicate the pad(s) slid out about 75% of the way, but still provided some reduced stopping power.
The slope of the last peak does steepen at about 75 MPH, presumably due to slowing down going through the gravel trap. Finally, things come to an abrupt stop at about 65 MPH.
This is scary shit...
