This year was the lowest by far, 15 dines (two surprises), 3,130 UA MP miles, no bonus points.
This was also the most problematic year; had one dine post at the member level rather than the VIP level and 2 dines fail to post. Eventually got the VIP bonus and one failed dine to post (almost 2 months later) but gave up on the other. Also giving up on the program. Driving home today from a family vacation around lunch time, passed near a town with 16 iDine restaurants. Decided it wasn't worth driving out of the way for a couple hundred miles.
