This one's not simply a tedious grind like when getting most of the other superstar ranks. You have to actually get really good at this game to achieve this one. The points start bottlenecking soon after hitting 1000 skillpoints and you pretty much have to score 200+ on every run to get decent points.
It took me a couple days of practice before I got consistent enough with strikes to finish this one. Very tough. I'm glad I'm finally done with all the bowling challenges.
