I tried the "Taspen's pattern" two times, but I didn't get, not a SINGLE red tank!

Best I can do is 60 stars, if super-tired, then 30 stars from missions. Also, do I have to wear a paint while earning stars?

Let's go gambling! Aw dang it! Aw dang it! Aw dang it! Edit: Is this different for everyone? Or everyone is getting the same results?
