Questions:

Which predictions, if any, proved incorrect as you increased the number of simulations?:

With a small number of simulations.

Suppose you're charged a fee for each second of compute time your program uses.
After how many simulations would you call the predictions "good enough"?: TODO

Predictions stabilized over 10000 simulations.
