well FF wants to see a sustained higher temp for at least 3 days post O. at first i thought that meant 3 higher than the suspected O day but no, its 3 higher than your average. so i guess thats why they said CD23. maybe you didnt get the cross hairs cause of the two drops after that. i dunno. you can go into the FF message boards and go into the VIP section (if you are a paid subscriber that is) and get one of their 'experts' to look at your chart and give you feedback.

sorry if i wasnt much help.
