It doesn't really make much sense, given the test frequency of Hobbit
or BB.

Most Hobbbit tests run every 300 seconds. 300 seconds is 0.012 percent
of a month. So the data simply is not detailed enough to warrant
reporting with more than two digits.

For reports covering shorter periods of time, it becomes worse. With a
300 second poll interval, you need to do reports for a full year
before it makes sense to show percentages with 3 decimals. (0.001% of
365 days is 315 seconds - so you can only have one outage on your
99.999% SLA before you're in violation of the SLA).

OK, you said your manager asked for it, so being sensible is not a
requirement, I suppose :-) In that case, change all occurrences of
"%.2f" in bbdisplay/bb-replog.c and bbdisplay/pagegen.c to "%.3f".
But that is one change you'll have to do on your own.
