It may be my internet., but in the mini games I always have some trouble. It's lag spikes and what not. for instance, when the speed changes during this game, it often jumps 4 or particles worth of the screen and I miss a lot of them. I still do pretty well, but my best scores are around 1200.
I'm going to create a video on this on Friday (working two jobs at the moment) but I've been using mission transwarps to get to the various places for scanning. Takes about 5 minutes total to move around and collect everything, so it works out great for me as I only have less than an hour per day to collect across all my accounts.
