You do know it's against adsense terms to discuss earnings in relation to impressions and clicks right?
It wouldn't be difficult for them to find out who earned $7.56 with 15 clicks by 8:25 on the morning of 31st of march. Or they could research your posts, See that this seems to be yours (pub-7374021828165185), And then see what that ID earned on the morning of 31st of march with 15 clicks. Either way, regardless if they know who you are or not, It's still against their terms. Just because you don't expect to be caught doesn't make it ok.
That is as clear as me saying I have $259.11 in my adsense today up to this minute. (I wish..) PS From 20 clicks
