Oh boy, time to bring out the D20.
I'll roll 1 D20s, if the result is higher than 14, you get an pass, but since you have come up with the idea of a rhythm and due to the training you have been through, it should lower to 12, anything between 12 and 6 should give you an neutral result.
And.... 14, you get a pass ! Lucky !
>You try to pick one size, but instead you have a new idea and pick 2 sizes instead after some good testing, one a tad over the ideal value, so alone it will overload the thing, but you also have an weaker one you know isn't enough to keep it fed, but maybe if you use those two you can find some combo that will work out !
