Microsoft routinely releases security updates on the second Tuesday of each month (Patch Tuesday), but can provide them whenever a new update is urgently required to prevent a newly discovered or prevalent exploit targeting Windows users.
The median typist speed is 38 WPM and the mean typing speed is 40 WPM. RankMyTyping.com, a typing test website that aggregates typing speed scores based on online tests, ranks the average typing speed at 43 WPM. According to RankMyTyping.com, secretaries that have taken the test rank around 74 WPM and the average 13-year-old performs around 23 WPM.
Comparison of typing speeds, like most other things, is very subjective. A typing speed of 84 wpm is certainly much higher than that of an average person. I'd say that most people who haven't learnt touch typing would key in under 60 wpm. If you're comparing yourself to such people, than yes, 84 wpm is really high. However people who do learn touch typing in can key in much faster.
