Touhou 東方実在相 ~ Dream Logical World Normal Scoring 27,691,912,310
I think most of the scoring strats are self-explanatory, but two points are that:
1) Purple invincibility circle indicates that you can graze during its duration, while white does not allow you to graze. This means you can and should use the start of your AS to run up to and graze clumps of bullets for easy extensions.
2) You get more PIV and score if your AS is forcibly converted by the end of a stage, than if you were to time it down. (The loss in SCB is also pretty large for timing down the final patterns.)
Messed up Stage 3 and Stage 5 fairly badly, will likely try to improve on it in future and aim for around 35 billion. For most players though, I do recommend trying out some of the easier grazes as even a small amount of scoring effort can result in gaining much more PIV than a pure survival run, netting you extra lives to work with for lategame.
