When to stop exercising length?

Currently, I have a BPSFL measurement at the 2nd of July which is 188mm with 48h after last length exercise to make sure a fair measurement. Since the 28th of June my pre-BPSFL has always been atleast 185mm (fluctuating between 185mm-193mm). If i full stop now, will my bpel catch up to about 185mm? will it be less? more? how much less? how much more? will my bpel stay as it is now? Or maybe how many days i should continue to make sure this length maintains?
