They will be even less impressed, however, if we fail.

Ils le seront d’autant moins si nous échouons.

I believe in it even less since the facts speak for themselves.

J'y crois d'autant moins que les faits parlent d'eux mêmes.

Now I understand even less than before.

Maintenant, je comprends encore moins qu'avant.
