Thank you both for the tips. I had never been to the Competition Forum. Now I have a problem... I'll want to compete all the time
Just did a fast try at 2x2 on the weekly comp but don't worry Marcel, I did not cheat with the 4th solve. I did it on yellow face on purpose to avoid that... and also had a terrible lockup in my CB 2x2 on that very solve, making it in fact the worst of my average.
My results
Not bad taking into account that I was nervous as if it was a real competition

I assume that for this comps, even if you don't have a proper timer you need to do a pick-up and throw of the cube, right?
Next week I'll try to do more events or maybe I can edit my post with additional events later this weekend. I will also try to enter the Race to sub-20 thread. I'm sure it will prove quite challenging.
