For the one against Jules:
I read somewhere that you have to count to four out loud to get the rhythm right. L1=1, R1=2, L2=3 and R2=4. (If starting position is L1)
I got it in my second attempt doong it like this. First one I tied with Jules, second time I won with 52-49.
And I have tried it many times without counting out loud.
Maybe this will help some people.
Now I need the cactuar crush and the 3D brawl. And a few ouders like Condor but that is just trial and error.
