Bravo.  Q3's revs of $302,000 is 239% of Q2's revenues of $128,000, but Q3's revs of $302,000 is an increase of 136% above Q2's revenues of $128,000.  Most people care about the latter.

In math, as in law, words have very specific meanings. In this ongoing apples and oranges argument about the percentage comparison of Q2 and Q3 revenue, the word "OF" is not synonymous with the word "UP". So you are correct in your calculation when using the word "OF", however you are not correct when using the word "UP".
