But that's exactly I am hoping does not happen.
If you see the excel worksheet in the thread started by kshashikanth..

The approximate duration between the 1st fp and 2nd fp is 16 to 19 months in most of the cases.
We may be nearing the 2nd fp and that I think, is the reason our cases are chosen for RFE.
A 2nd fp is at no cost to the filer. All the expenses are borne by USCIS. I feel that would be one way of cutting cost and also expediting the approvals.
My 2 cents.
