I personally don't have a problem showing inexperienced riders the ropes. At first I was ok with the flat bar road bike, but than we were regrouping way too many times. In my case I have to consider the riders that can ride at the advertised pace which like yours turns out to be a 14-15mph average. By constantly having to wait for the others does not make for a fun ride for them.

Up until the days got shorter I began another shorter ride of 14 miles on the day the shop closes early for the riders that could not ride up to speed and for new riders to give then a idea of what our weekend rides are which are but double the mileage. We are slowly trying to have a group for everyone.

When my group rides end next month I offered to work one on one with 2 ladies so by April they should be able to ride with my B group.
