I don't know, I read all the posts here and I really was interested in the topic op decided to go for. I mean, I'm not exactly doing this since 10 years or so, but I am nearing 2 years at least.
I am a premium seller with options, mostly on equities, sometimes ETFs, but more interestingly futures (CL/NG). I'm not one of the degenerates from reddit's WSB or theta gang - I know how to risk and money manage and I don't like leverage. So, it's not just that I don't leverage, I actually deleverage: Being short vol most of the time, I hold around 0.55 of my bankroll cash as collateral and actively play the corresponding 0.45 of the bankroll as actively used collateral for premium selling mostly on a monthly basis. This is supposed to result in 10-12 waves of trades a year. However, I do operate on the 0.55-cash-collateral, too. Very safely, or at least, as safe as can get, so there actually is some kind of gain on this 0.55-part, too.
I actually managed some heavy drawdowns in Feb/Mar '21 on short puts this way (upper 30% range on numerous positions) quite ok, so I guess and hope this counts as a risk management which is kind of resilient.
Now to the 1%/month-thingy: Totally ignoring what comes out of the 0.55-part of the bankroll, I intend to score 1%/month (for the total of the bankroll that is) by way of this strategy, and I must say, that I overachieve - not exactly by far, but still - significantly.
So, all in all, I guess, this is my take on a 1%/month strategy. But it consumes some time in my case.
EDIT: Just to add...maybe I sold myself too cheap here. This is indeed delivering way above the 12%-mark/year. All in all, ignoring the fact that 2021/22 were good years, I estimate this approach to deliver close to 20-25%/year pre tax.
