^ I completely agree with your regarding the lack of consistency there, because our latest rulings have said that the size of the score doesn't matter, and that was the entire reason for Sky Chase having a chart.
...well, I don't agree on the death Egg point, unless you can propose the cause of it, really. At least with random rings, you can say that it's truly random, but if this is completely unexplainable, then definitely not. I've edited that boss before for my hack, and didn't see any code that could cause double points.
