Have you been using the car between checks? 

Also, this time of year it pays to give your battery a top-up charge occasionally

It's just been sat there for 3 days only use is opening and closing the doors and setting alarm it was fully charged up sunday

On my limited knowledge I'd say that's normal if you have been opening /unlockingvthe car on and off for 3 days then you would expect some drain of the battery as the car will probably go through a process once you unlock/ open the car and the reverse when you close it/ lock it each time.

Have been monitoring my 2020 Fiesta daily over the passed year via my tracking censor. When not using the car over a three day period my readings match yours almost to the decimal point. So I don't think anything to worry about.
