Sperm meets egg plan?

Hey ladies! 
First time posting here... This month the hub and I are trying the "sperm meets egg plan" which pretty much says to use opk's to detect ovulation and once a surge is detected, have sex 3 nights in a row- take one day off and then have sex one more night. 
Anyone tried it?
