Thank you sniperssk, gottabwise, rhyme, Jerz and Milie for your inputs.
My second recommender submitted the recommendation y'day and I didn't have the opportunity to talk to him about the ratings. I don't know how he has ranked me. Perhaps I'll have a talk with my third recommender. The thing is that all my recommenders have at one point or the other been a mentor to me. And are naturally as excited of me applying to b-school as I am. So I can understand their enthusiasm.
I am leaning towards the reasoning given by sniperssk. I'm sure if the adcom have any doubt they'll call up the recommenders and my recommenders can then explain their ratings. And as far as anecdotes are concerned, I'm sure they have mentioned them in their essays.
Thank you all for the replies.
