likuair,

YOU can do this.

Check out the GETJPI call in the example.
Read it twice.
The GETSYI call is very much similar.
Read up! In the manuals, or: $ help system $GETSYI


As for the 20%.... 20% of what?
A single CPU? All cpu usage?
Since beginning of time? For an iteration?

YOU can do this. If you can not, then IMHO you have no business even asking the first question.
YOU can solve this in the program, or outside in EXCEL.
You'll just need 2 (or more) measurement in a loop. Take that CPU time (in centi-seconds) subtract the prior value, multiply by 100 and divide by the centiseconds between measurements.

IF you can not handle that, call LIB$SPAWN ("SHOW SYSTEM") or similar.

btw... For mere money I'll gladly hold your hand, or do this for you.

Enjoy!
