i do know math lol, and i can share with u a screen shoot or a video with right PEN and lower acc and stage fail if u wish forseems like u dont know the math. So u need 70% of pen/acu thats what u say so if thats true I cant do that stage since 70% of those are as following:
pen:179,9k; acu=154k so that means I have not enough with 145k acu, only my pen is over 70%, but wonder I didnt fail the stage seems like u do something else wrong.
