Yes. If you establish a safe OCI (for example, 2 years, let's say), you can continue to do that without paying for a UOA each time. If you just blindly change the oil each year, all those extra changes using synthetic oil could be expensive (especially if the OP uses boutique oil).
IOW, a one- or two-time expense to establish a good OCI vs an ongoing and likely unnecessary expense.
By your logic, one can do 1-2 oil analyses to determine their interval, but for how long ? Conditions change - engine wear, oil formulation, and so on. If you're going to spend $25-30 to analyze the oil, that's just silly. Spend that same money and just change the oil !
You bring up a good point, and that was my logic until I was able to buy Wix oil analysis kits for under $10, TBN included. Now it is a little higher but well below $25. Anyway my driving conditions remain the same so the data has proven to be cost effective and useful.
I just bought 10 of them on Rockauto for $9.52 each and my total for FedEx was something like $7.92.
