I'm not suggesting that they may be useless; my point is that we should not
copy/use things without questioning whether they fit the bill. To that end I
simply asked questions that came to mind :)
We now have 1, 5 and 15 minute rates. Are these enough? Do we maybe need
sub-minute rates? Do we need an hour rate as well? Essentially, why these rates
and not others? Could the 1 minute rate be enough for us?
For each added rate a given processing overhead is created. Is this
overhead worth it? Should we force this overhead on every Meter user even if
they only use a single rate? Should we maybe not hard-code different rates but
make them configurable (somehow)?
Why do we need an *exponentially weighed* 15 minute rate if you can get a
closer look at recent events with the 5 minute rate?
