You need to specify which parts are being modified by an SRS system: each card has an easiness parameter and that will be continuously modified based your performance, but I don't think existing SRS systems like Anki or Mnemosyne will modify other parts of the curve like the exponent. For example, SM2's algorithm runs in part based on updating the easiness as EF+(0.1-(5-q)*(0.08+(5-q)*0.02)) - the EF will be progressively updated, but the formula itself never changes even if 0.1 is not ideal and 0.15 would be better or something.
