A CTR that high is usually a result of either poor content or ads masked as content
Are you trying to say that google ads are so good than the content and people find them more relevant to click through them? :)
Well, don't worry about CTR and other stuff these days as we never know how correct they are..it is just what google gives you at the end of the month that counts and that will not change much unless your traffic changes.
if you almost have the same traffic for two or months, you will find that google gives you almost the same money on each of those months.you may have different CTRs , EPCs and whatever for each of those months but the total money that you get will not vary as much.To me all those stats are there to just fill up those reports :)
