Start with the following parameter vals:

Learning rate eta = 4.0 
Shifting rate alpha = 0.08

Reasonable spin_down_costs are 1 to 20 seconds 
which translates to
     1 * 10^6 = 1,000,000  ms.
 to 20 * 10^6 = 20,000,000 ms.

Use 100 experts with time out value from 
0 to spin_down_cost (spaced linearly, harmonically,
or exponentially). 

The data visualization on the 242 webpage 
is correct, but the x-axis is labeled 
incorrectly as seconds not microseconds.
