I think both Vincent and me are basically fine with the patch, it was
the Changelog/explanation for it that sat uneasy.
Specifically I think the 'confusion' around the PELT invariance stuff
I think that if you present it simply as making util_est directly follow
upward motion and only decay on downward -- and the rationale for it --
then it should be fine.
