Tell us what is wrong, or who is missing
Think our math is wrong? Prove it.
The rules are summarized publicly; the full formulas are available to registered members. The method is a hypothesis we test, not a verdict. If you can show a better rule with evidence, we will change it, and we will credit you by name in the changelog if you agree.
Mathematicians, statisticians and analysts especially welcome. Read the rules first: the math, the backtest plan.
