"how you're measuring drawdown"

The front-month futures contract trades for three months. For that contract I set "max_account" equal to the account balance on the first day of trading and "drawdown" is set equal to zero. At the end of each trading day for the life of the contract "max_account" is updated to the new account balance if the new account balance is higher than "max_account". Next "drawdown" is updated to "max_account" - current account balance if this difference is greater than "drawdown". So my "drawdown" is the maximum decrease from the maximum account balance during the life of a given contract.

Actually, I miscalculated the drawdowns in my other post. They are too large because I did not reset drawdown to zero when the new contract started.

I could calculate drawdown for the entire life of the testing period, 20 years, but it changes so much from contract to contract, it is more useful for me to monitor drawdown on a smaller time frame. Since my system is profitable most of the time, the overall drawdown is not going to be much different than the largest 3-month drawdown.
