The whole point is if there's not enough ram of course... this is why

The numbers will change depending on what's running on your
system. It's up to you to know plus I normally keep vmstat monitored
in the background to see how the cache/free levels change over
time. Those numbers are worthless if they could be fragmented...
The admin should do that if he's unsure, not a program of course!
