> We've seen intermittent failures in this test because of the change being out of the pre-defined range. The largest "out of bounds" we've observed is 1.5MiB, so increasing the fudge factor to allow for 25MiBs more/less should be sufficient for us to not see this error for a while. This kind of adjustment is an unfortunate necessity when developing these kinds of tests.

Johan Sjölen has updated the pull request incrementally with one additional commit since the last revision:

  Split fudge factor and stop at C1
