Best day to bd?

GMC

If I bd tonight there is a 26% chance but if we wait until tomorrow there is a 30! According to the app (we bd after midnight since he works so late so I’m using the next days percent.) it’s only like 1 time every week for us. I kinda don’t want to wait since he may have to work later Thursday and not be into it. Though try on Saturday too since it’s o day for me. And we have the am together, before he has work. I want to bd more often than him. He’s basically content with once a week. Not sure what to do for choosing the right day.
