There is nothing wrong with engaging in techniques to improve DCA, which truly if someone is new to bitcoin, they might start with a certain weekly amount for their DCA, yet in the meantime, after several weeks, they could be figuring out various aspects of their budget and maybe how to employ their DCA better.  On a personal level, for the first year that I was in bitcoin, I tended to give myself a weekly DCA budget (or allowance), so during the week, I would try to maximize the buying on dips within the week, however, if I had not used all of the weekly allowance by a certain time of the week, I would just buy with the rest of it at that deadline time in each week, since my new weekly allowance would become available at the beginning of the next week... but yeah sometimes going through the process, with the passage of time, I was able to figure out some ways of employing my DCA that worked better for my own circumstances... but also recalculating my situation, that surely went even beyond the first year, since the strategies became different with the passage of time (as you suggested might become the case for anyone going through their BTC accumulation journey) and the fact that I had been accumulating BTC through the previous time and the details of that prior stacking in regards to how much, what was the average costs and considering whether my stacking goals were changing and/or close to being met, helped to inform any changes in my practices.
