How much a build's time moves from run to run on the same machine: the run that 9 runs in 10 beat (p90), over the typical run (p50), for each build on the machine Real builds picks, averaged over the builds with 3 runs or more. +10% means one run in ten took more than 10% longer than usual. A line measured on one build is shown, not ranked.
