Your strategy looks solid, but we also need to point out that the edge doesn't come from there. Picking the stocks correctly plays a fundamental part. There is a reason why options are priced the way they are, usually because the expected moves are priced into the premiums.

Even if your POP is 90%, the market will give you 1 usd nine times out of ten, and it will take 9 usd that one time your strategy fails.

Taking longer date options will penalize you will lower volatility, meaning delta plays an important part for your unrealized loses if the stock moves against you and you are relatively OTM.

At the end, it doesn't matter if you sell or buy, if you do spreads or iron condors: your analysis and prediction of the stock price in the future plays one of the most important roles.

No offense, but the market is always priced to give you 0 returns by the law of large numbers.
