Drawdown
Standard max drawdown 14.9% vs rule 8.1% (-6.9 pp).
Assignment
Assignment rate 33.3% standard vs 21.1% rule; call-away 37.5% vs 14.8%.
Fallbacks
The rule arm held 0 of 46 short options to expiry because no 21 DTE price was available for the buy-back.
Data quality
Real option bars priced 47% of the standard arm's entry fills, 46% of the 21-Day arm's, and 46% of its 21 DTE buy-backs. The rest are modelled from implied or realized volatility.
One ticker and one window cannot prove a rule works everywhere
Simulated fills can differ from what a real order would have gotten
The rule arm sometimes cannot exit at 21 DTE and falls back to expiry
