Please do not worry about the initial LUD changes. It's very normal process. The time after first three/four LUD changes varies. It's any anywhere from two weeks to six months. I had two RFEs and then an approval. Between 1st and 2nd RFE, it was a gap of three months. 100/M profit per year, is an absolute winner(I'm surprised why you even got an RFE). Next LUD change will be your approval, do not worry.
