Spaced Repetion System card selection

Hello everyone,

in the SRS Card Selection, will it do harm to the repetition system to alter the Points Per Day number frequently?
For example, having around 4000 cards altogether, to have a card repetition number of 150-250 per session I'm forced to fine tune that figure between ca. 33 to 37, sometimes on a daily basis.
I wonder if such interference will compromise the algorithm's proper function.

I understand as yet there is no way to set a maximum value of repetitions, as this would defeat the SRS idea?

Thanks so much in advance!
