Early Pregnancy Signs point system in FF

Hi! What do you think of the Early pregnancy Signs feature in the Fertility Friend app? It tallies symptoms on a 100 point scale, with totals over 70 being 5 times as likely to be pregnant. Last month I was at 95 points by the time my period arrived! This month it seems to be adding points much more slowly, as if to caution me that last month was too high. I'm currently 8 DPO and just at 5 points! Is this FF feature worth paying attention to at all? Thanks for your thoughts.
