Trying again today on MP4, 7 runs no key yet.
Don't remind me the 5 nv rule, I'm not stupid enough to try 20 times without knowing that.
just do the math. chance of mp4 7 runs no drop is 2.7% and the chance of 20 run doesn't drop on MP3 is 0.08% !!
A1 and A2 seems normal, just A3 is odd.
Anyone ever run into similar issue?
