Accuracy in game review is difficult to interprete

I noticed with interest that there is this new feature on lichess. However, I find it hard to interpret - what does it say?

I have checked my games, and in some games, I had a worse (i.e. higher) ACPL and simultaneously a higher accuracy. How is this possible? Also, I saw that my accuracy differed significantly between games where I had a similar ACPL.

How exactly is the accuracy calculated and what is it supposed to tell?

Thanks! This is exactly what I was looking for! :)
