--Alpine Armored Train
The pods are worth about 1000 pts. apiece, and you can probably destroy 10-12 before the boss self destructs.
Pods are worth 500 pts. apiece + 150 in e-cubes. Eight are released at a time, so that's about 6000 pts. each batch.
Boss pods are worth 2000 pts. apiece (500 + 1000 (p-up bonus) + 500 (large e-cube). With three groups of three, quickly regenerating, this is probably a 50,000-100,000 pt. milking zone.
There are about 56 enemies on this stage that slowly sprout an additional 4 small e-cubes (the most out of any stage). Total it's about 11,200 pts. extra, if I counted correctly. Also note the section before the halfway point, if you destroy the midboss quickly you can get extra sets of small enemies that are worth about 5000 pts. total.
--Stage 7 (forgot the name)
The boss has the major
amount of milking. First form, groups of 8 pods. The pods are worth about 2200 pts. apiece, 17,600 a batch. It releases at least 10 of these before moving onto the next form. Final form, boss surrounds itself with about 8-10 rocks (didn't write down the values, but probably about 2000-3000 pts. apiece). Then it shoots out 20 or more pods like before, at least 40,000 points. It does that twice before self-destructing. 300,000 pt.+ milking zone.
The first orb (blue) on the inner structure releases many blue crystals that are worth 1000 pts. apiece. I'm not sure how many can be destroyed before having to destroy the orb. I'd guess 20-30 or more. And like the midboss on stage 6, if you destroy the 2 mechs quickly you can get multiple sets of extra enemies.
So I think I've got about 1,700,000 pts. accounted for each round, and there's the 10,000 bonus for each remaining life (30,000 possible). The WR is about 400,000+ pts. more than that, so there's definitely some tricks or glitches. Bah!
