I also applied a similar methodology to Calendar Puts over 5/7 days, predominantly for the cash-settled Mon/Wed/Fri cycles (Nasdaq, Russell 2000 and S&P500) which has gone well.
These take considerably less time to run simulations for, but I only expect to get 6-8 set-ups per month. 24 out of 26 trades have closed in profit, with average profit of 21.3%. I'll try to add them here in future. the last few trades were:
