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.
With that example that you gave Nwada001, there could be adjustments of the timeline in order to accommodate that some circumstances had changed, so maybe there is a realization that the goal might take 14, 16 or 18 months rather than the initial 12 months might not have been as realistic as it had been originally thought to be.
Persistence and consistency are also two differing concepts.
