The report performs the stats on the downtime. If Linux had an annual downtime of 19.5 hours and this was 20 percent more than w2k3, then the ratio is 19.5 / x = 120 / 100, where x is the amount of downtime for w2k3. Solving for x, we see that w2k3 has an annual downtime of 16.25 hours, a difference of 3.25 hours. If Linux had an annual downtime of 10 hours, then 10 / x = 120 / 100; thus, w2k3 has a downtime of 8 1/3 hours, a difference of 1 2/3 hours.
