I mentally replaced “100” with “N” anyway

You mentally threw away relevant information. ie. You merely made yourself incapable of thinking about what is claimed about the size of c relative to 100. That's fine but ought to indicate to you that you have little useful information to add in response to a comment that amounts to an expression of curious surprise that (c << 100).

(and interpreted “almost N” in the obvious-in-the-context way).

Where the context suggests it can be interpreted as an example of the Eliezer's-edits bug?
