Sperm meets egg plan

I have heard people have great success with this plan! I have a question- the plan suggests having sex every other day starting CD8 until you get a positive opk. Once you get that positive you have sex that day and the following two days, skip a day, then have sex one final day.

My question is- do you think this applies to women with a 28 day cycle? I have a 29 day cycle so if I follow this plan I would end up having sex 4 days in a row during my most fertile window instead of 3 (I get positive OPKS CD 15-17, and on this plan you also should have sex on CD 14 because that falls under “every other”).

In that case do you suggest I do this plan but start it on CD9 so it lines up with original plan? Any help would be appreciated!
