Your Math is spot on.

Has anyone actually tried using 4 level 1 earthquakes to check if they can destroy walls ?

In this reddit post https://www.reddit.com/r/ClashOfClans/comments/3bqz3g/earthquake_spell_op_strategy/, the OP seems to be using 8 level 1 earthquakes to destroy walls (this would be consistent with your math above and the 20%[unconfirmed rule]).
