BimmerLink misfire counter

I have a 2017 m3 with the s55 and 56k miles, I had tried the misfire counter with BimmerLink and it showed over 80 misfire on cylinder 4 and over 500 misfires on 6, I tried it again maybe a month later now showing over 30 misfires on cylinder 5 and 3, and now I just changed the spark plugs, used the misfire counter again and it showed over 20 misfires on 1, 4,5 and 6, I thought the car felt better then before, all these misfires were under load, the car runs great, it always has, no CEL, no codes. So my question is my car fine? Is BimmerLink not that accurate with that kind of stuff or should I be looking more into it?
