Fertility Friend & Ovia

When logging Clear Blue Advanced Digital OPK (H, P, L) into Fertility Friend do you log both peak days or just the first one? Since it remains a solid smiley face after you get Peak, I am not sure if I just log it for one day. I didn't originally have the 2nd Peak day recorded with a P but when I tried to add it, FF said it could not longer see a clear ovulation pattern and has to reassess. That is so wierd that the recording of one peak day would remove my coverline and red ovulation line. Also for those who track BBT, do you like FF or Ovia more? Which do you think is more accurate in reading your ovulation when entering temps, CM and OPK?
