One of our new members, malfos, has just picked up a 2015 Glee and the owners manual has the additional sheet in similar to the new 1000 that shows the new service interval as 7,500.
" One point of interest is that in the service book,there an inserted page that shows the service intervals for the 650 AL5 model, have been increased to 7500 miles"
So they've finally confirmed what we knew all along, they were over servicing it.
