Efficiency is the percentage number of days in your current cycle that
PERIMON determined as infertile*. The efficiency is highly dependend on the regularity of your cycle. Apart from that in most cases it is not possible to exceed a pecentage rate of 25% until at least 92% of the “
Learning phase” was completed.
Please mind that the rhythm method has its limits and that we know these. If
PERIMON isn't forecasting, it is just about right. You then have to use additional
methods with which you examine your body daily during the unclear period. In most cases these methods lead to definite results, that give you additional days that are clearly infertile. Please understand that in your own self-interest
PERIMON is silent if it has to be.
