Mine took 9.3L the first time, and 9.5L the last when I also sucked the oil filter housing dry (exactly 0.2L in there). Next time add AT LEAST 8L man, but I'd do 8.5L after a thorough drain; at 7 you were too low. Remember you don't want to be more than 1L low. And yes, it's better to go 1/2L at first when you get the '+1' message, then 1/4L at a time until full.
