And about the *classical* Bootstrap, what just happens?

Permutations
___________Exp.I__Exp.II_Exp.III__

Bootstrap
__n=20_____.985___.984___.980__
____25_____.990___.979___.993__
____30_____.990___.994___.988__
____35_____.992___.994___.989__
____40_____.993___.990___.995______total=14.836

No difference between the two algorithms, the advantage of Bootstrap is that is faster, however Permutations is more convincing because do not admit a item be present in each pseudo-sample more than one time: the complete permutable propriety is what´s demanded only.
