RMS by default shows 1x/1x/1x rates. There is an option to change it to show specific drop rates (as long as they aren't altered even further).
For our server, that would be:
Base Exp: 5x
Job Exp: 5x
Drop Rate: 3x
At those rates, it should be 500k base exp for the normal monsters; 90k (18k*5) for the MVP summoned slaves.
