Yeah, that script makes sense, but what does the 'average' std deviation of the 10s intervals really mean? i.e. This is the mean of the std-deviations and the mean of the maxes and mins, it's kinda weird. Mean of means is probably really close to the true mean, and the mean of std-devs is probably close enough, but min / max seem odd in that it's the mean of the minimums of each 10s interval.

Anyway, stats are never perfect, but I'd vote for dropping the min / max and use the mean of `mean_90`
