Comment (by simonpj):

 But these figure are

 * deviations from the "expected" stored in `all.T`

 That's quite different from

 * difference in allocation between just before the patch and just after
 the patch

 Maybe this 3.6% was there before the patch!

 Also, it'd be good to know what "the patch" is when showing the
 differences.
