Unfortunately, rules, especially rules of thumb, are meant to be broken. For example, your 99% critical may not apply. We have experienced long periods, sometimes as long as 8 hours, with the system running at 100% with no complaints about performance. Similarly, pre 5.2 days, we regularly observed very high rates of pages moving back and forth between main memory and XSTORE, with no complaints from the users about performance.
As the performance guys like to say, YMMV (your mileage may vary).
