### Envelop of the spread of difference norms
We can see from the above plots that the difference of norms of $`\Sigma(k)\Sigma^{-1}(k)`$ and $`I(k)`$ is flaring up after a certain rank.
We can see from the above plots that the difference of norms of $`\Sigma(k)\Sigma^{-1}(k)`$ and $`I(k)`$ is flaring-up after a certain rank. We can set a number for the flare-up by looking at the envelope of
the spread of the difference of norms. The spread is basically the standard deviation of this quantity.
