>So, if you’re targeting 95% CPU utilization in a web service, the maximum amount that the service scales out after each cooldown period is 11%: 100 / 90 = 1.1

How many errors are in that sentence? The 95% -> 90 mysterious conversion. 100/90 is actually 1.111(repeating of course), not 1.1. And if it did equal 1.1 it would be 10%, not 11%.
