I'm wondering what you are allowed to communicate and what not. I know you can't disclose CTR's. But would it be allowed to state your visitor numbers based on a statistic tool (StatCounter or whatever) and state the ammount of clicks from adsense? This wouldn't give a trustworthy CTR, since the visitor numbers differ strongly from the AdSense numbers.. Furthermore, can you state your earnings, and thus the $ / click you are receiving?
Just don't take a screenshot of your Adsense CP, with all your stats, and show it to the world. People lie about their earnings/clicks/impressions all the time, so just juggle your numbers, or approximate it.
