My current weekly gain is around 3-5% against total account capital/liquidity but was less before I got things properly worked out. I have achieved 7% but that was pushing it or just a crazy week to trade. My target is 5% and I see this being achievable unless I hit a bad week and then need a recovery week. I could achieve more if I didn't have mostly shares in the accounts as only about 1/3 of the share value gets released as excess liquidity that I can actually trade against.
I've recently started an experiment with a couple of my sons, one through my account (shadow accounting) and one through his own new account. Taking one for example, he started with around $5k excess liquidity, and is using half that amount as the margin limit to sell options against each week. So far this is yielding weekly option premiums of $4.25-$6, so say around 10%. At first this only allows for one contract per week but will build into additional contracts as the capital compounds. If we can keep this up for a year, then I won't have my kids coming to me asking for money.
Edit: Added graph for the last month for my main account:
