Planning is the first stage of anything that is associated with consistency. It is following the plan that is called consistency. DCA is itself a plan and following your DCA is the consistency.
I get your point, but I don't see consistency as just following your plan, as plans can be followed in different ways. Let me say, for instance, that I have a plan to accumulate 1 Bitcoin before the end of one year, and initially I strategize to buy another 0.08335 before the end of every month. In the first two to three months, I was able to achieve that, but because of some kind of personal issue, you decided to shift out the amount you want to accumulate this month, but with the belief that you will be able to gather more than you plan for the next month so that you can cover up the balance of last month.
In such a case, I don't see that as consistency, as I view consistency as the process of doing a particular thing constantly, nonstop, until the purpose of that thing is achieved without even bridging any of the set-out plans along the way.
It is very common that you make a plan and within a certain period of time you implement that plan but in between some time your actions to implement that plan are erratic. It is normal for this to happen in terms of personal needs or family needs. I think the big thing is whether we have been able to implement our plan on time. In one month I may need a lot of money and in that month I must deposit some less amount than the specified amount but in the next month when my need of money is less but the amount I kept less in the previous month will be kept in the same amount in the next month as well as the money of the previous month. I can keep in this case that my needs are met and my plans are implemented at the right time.
