Once again nicely explained, and I really like your contributions. Still, be careful.

Is 80% what you have modelled for, or what you would endure if need be (but you modelled for much lower drawdown)? If former, I think you're in a world of pain. If latter, then I can agree with you.

Put another way, if excessive leverage brought your account to only 20% of previous value, and if you continue applying the same position sizes, your risk is now 5 times bigger. While you're right that only such a big risk would ever stand a chance to bring your account back to the previous balance, in reality you're probably just a losing trade or two away from a margin call. The leverage was too big previously, but after 5 times amplification it is simply devastating.
