|Metrix » Tuning|
It depends upon what you are using Metrix for. If you are using it to demonstrate savings for a performance contract, then by all means, no. If you are comparing usage and costs to a given year in the past, and as the years go by, you expect to continue comparing to that same base year, then, no.
On the other hand, if, every year, you want to compare to the preceding year, or something like that, in which your comparison year changes every year or so, then yes. Every year you would select a more current tuning period and then tune it.
