Seems to be failing in blink_style.py (https://cs.chromium.org/chromium/src/tools/perf/measurements/blink_style.py?q=blink_style.py+file:%5Esrc/tools/perf/&sq=package:chromium&l=140) with a float division by zero.  This doesn't seem to be failing on any other windows bots so I am assuming it has something to do with these specific windows bots.  See relevant stack trace below.

Ben, Ethan, Ned, do you have any telemetry insight into what values it is trying to pull here to determine why they might be zero?  Seems like part of the trace event.
