I am a little confused on the new instructions to the New Choice Ovulation Predictor from Dollar Tree (took a pic from Google because I have already disposed of the box)

So, does this mean basically the darker the line the more of an LH surge there is and the test line doesn't have to be equal to or darker than the control line? Because I had a very faint test line Thursday, then had a darker line almost as dark as the control line but not quite on Friday but I had already BD around 12:30 AM and the test was done around 5:00 PM later that day. I'm really hoping this is my month. Last few months I waited until about 24 hours after LH surge which I kind of had to due to work schedules, etc. This time, if I calculated right, I BD 2 days before O. Going to most likely BD again today to be sure. I'm not sure though because the line got lighter upon testing yesterday, but it can't hurt. Lol. Any advice or suggestions would be great. I basically want to know if I understand the instructions provided on the box so I know that I timed things properly. Thanks!
