I read an article recently where the author generates randomized profit data based on a %Win and Profit Factor.

Based on this data's standard deviation and mean he then creates a theoretical probability distribution.

I created an actual distribution (in red) using Excel's FREQUENCY function to determine if this is approach is feasible?

Based on limited stats knowledge the two do not compare well at all (see attachment) and I'd like to determine if I have made an error or if this article is incorrect in assuming the theoretical distribution could approximate reality?
