Monte carlo
Spent the morning running my Horse back systems through monte carlo simulations.
Here are the results per staking plan.
Based on 100,000 simulations per system.
Back system 1:
Systems performance to date looks like:

And what it looks like to level stakes, percentage & Square root:
Back system 2:
Systems performance to date looks like:

As you can clearly see.
Having a winning system is only part of the story.
I am currently running my lay system through 100,000 simulations.
Will update once complete.
