I speak out this paradox, as I have been testing myself continuously with MGMAT CATs and GMAT prep CATs, have used new tests for ESL to check grammar soundness, the Princeton's manual for CR entries and RC99 passages - all indicate that I am able to answer correctly AT LEAST 90% of entries in Grammar, 75% in CR and 65% in RC.
I am sorry to hear about your verbal score. I did score V16 too a week ago, and I thought there was something wrong with there algorithm. But no, GMAC has responded and there is nothing wrong with the score.
I have no idea how you studied, but maybe you should try to analyze whether you were missing any important details. For instance these are things I left out:
- Didn't improve my reading comprehension or speed by e.g. reading magazines/papers
- No
careful review of my mistakes although I had an error log
-
Skipped the last long RC passage by random guessing four questions which I think dramatically affected my score, say 4 RC Qs wrong in row... 
- I did not read SC for meaning, instead I tried to only attack by grammar rules which probably trapped me on the real test when I couldn't find obvious grammar errors in some sentences.
- I thought I could do GMAT magic in a period of 2-3months, but I couldn't.
- Watched the timer, calculated how I was doing pacing wise etc, probably 10 times during each section which impact the timing/stress
- Did not consistently score near or above my target score on practice CATs
- Studied to intensively
Did you repeat CATs? That will change your score dramatically..
I have been on a break for more than a week now to recover from a
lowered GMAT score than my first attempt. I have also ordered some new books and will now go with the Veritas book set and try to rework the GMAT concepts. Finally, here is a video I found motivating
