I am not sure if it is just the reviews I am reading or what but it seems most of the k girls review are : shower-> slight bbbj/daty-> sex. Is this a typical routine for K girls? I understand there could be so many variations here but comparing their reviews vs non-k girl reviews it seems more "routine" than others....
...can see up to 10 guys a day. That's why they have a routine. They have to get you in and out (pun intended) expeditiously.
Yet their escorts can't innovate in bed and sticks to the same routine! 
My guess is it's the agency instructing them how to do their job right from the moment they started out,
I also haven't seen too many "agency K girls gone indy" who regularly post on TER.
Your reviews are east coast but Boston - Providence - NYC routines all seem to be different. I don't know DC or Baltimore. When it comes to a KMP, there is good reason to keep things fairly formulaic. In NYC, the girls can mix it up a little bit and let their personalities shine through but the competition to outdo the others is diminished. They are ALL going to spend some time with the peripherals, provide similar level of service (7 maximum) and finish in a timely fashion. (I'm not including the GFE option, just the regular non-GFE.)
Indy K-girls have much more variation. The NYC reviews may describe similar sounding routines but they the range is much greater. Boston K-girl indies are more comparable to NYC K-girl indies
