Nah don't worry about some hypothetical better way, it doesn't exist. Your experience is more valuable because you know what works for your body and training. 1 week cut/bulk cycles are a bad idea though because you never give your body a chance to 'adapt' to fat loss / reduced calories which is what you need to burn fat efficiently. Keeping a weekly deficit but eating more calories around training helps you recomp and recover from training, which makes sense and seems to work well in practice.
If 1 week cycles never give my body a chance to adapt to fat loss, then what about cycles even smaller than that like i’m currently doing?
Then you will have sub-optimal fat loss. you have to pick your priority but you've picked a small amount of fat loss so you can maintain (and perhaps slightly improve) your overall performance which is reasonable if that is your goal. If you were prioritising fat loss you'd have a weekly deficit with perhaps one training day where you go on a +500kcal surplus, the other training days would be smaller deficits or even maintenance. It's a choice based on your goals. The problem with doing 1 week cycles is that you will go from carbohydrate metabolism one week to fat metabolism the next. It will be inefficient at either goal and the transition between the two will difficult physiologically and psychologically. The body adapts better to something you do consistently. On the week you eat more carbs you won't get much fat loss and when you switch over the following week there will be a challenge to switch to fat metabolism and vice versa.
One suggestion id make is to keep protein the same on all days, will help with adherence and satiety. The macro you want to play with is carbs. Use more around training and less when you're resting. Find the right amount you need to eat every day so you can sleep and function normally and eat a bit more than that when recovering from harder training days. But your experience with what works best for you is going to trump any of this so let that guide you.
