Hi folks,

I wonder how to solve the example 5.3 on page 174? I tried to come up with the right solution, but the outcome doesn't make sense.

These are the given numbers:
Hitrate: 52.1%
Number of test days: 500

The correct result is a cumulative profit of 22%.

How do I get 22%?

Thanks a lot and have a nice day!
