I want to comment that Etot vs Ecutoff is converging very slowly, and 
looking at that curve one might want to go as high as 800Ry.
On practice people usually say that mesh should be good enough to avoid 
the eggbox effect.
Anyhow, using %block GridCellSampling is a good alternative to 
increasing the mesh cutoff.
