I think the question is whether we want to make this useful for other places and/or people, or if it's fine to tailor this specifically for the freezing patch. If the latter (specific to the freezing patch), I don't see why would it matter what we think - either it works for the patch, or not. But if we want to make it more widely useful, I find it a bit strange the relative accuracy *increases* for older data. I mean, we start with relative error 6000% (60s/1s) and then we get to relative error ~4% (1w/24w). Isn't that a bit against the earlier discussion on needing better accuracy for recent data? Sure, the absolute accuracy is still better (1m <<< 1w). And if this is good enough for the freezing ... > Column 1 over column 2 produces a line like in the attached pic.
