I think you missed my first paragraph, where I made that point:

"Normals" are using their name with a 3 instead of an E, or some word with a 1 on the end. This tends to put them in rainbow tables _or_easy_attacks_.

Also, my example passphrase that I was annoyed Evernote wouldn't let me us isn't log2(2048^4), but ~ log2(5000^8) even assuming you know it is words.

This thread is getting of on the tangent of debating XKCD's particular formula. XKCD is not the point.

My original post asked Evernote Team to please grok the idea of that cartoon, which it's obvious they had not given their clearly wrong tips and rejection of a very strong password and acceptance of one of the weakest.
