Fig. 1 shows what my multiplier is at certain points in the game, usually after I use the reflect force. For the boss, I have these multipliers and item values:
First form:
- TIME 85, front two gun turrets firing needle bullet clusters upward and downward: x2790511, +2935.
- TIME 75, rear rotating gun turrets scattering bullets: x3527007, +3176.
- TIME 66, side gun batteries open: x4014732, +3326.
- TIME 56, central red gun turret scattering ring bullets: x4647247, +3511.
- TIME 51, side turrets firing twin vulcan shots: x4967332, +3601.
- TIME 39, rear gun turrets firing needle bullet clusters upward and downward: x5336184, +3703.
- TIME 25, boss is along the left edge of the screen: x5734267, +3808.
- TIME 19, rear red gun turrets scattering bullets: x6190632, +3926.
- TIME 12, boss firing short lasers: x6265416, +3945.
- TIME 0, boss firing winder: x6823501, +4084.
- TIME 0, boss escaping: x7074516, +4145.
I would also like to know the score and multiplier breakdown from plays by the ARCADIA record holder or YMN. That is, I would like to know either of their score and multiplier at the end of each stage trip and stage boss.
One more thing: when is it beneficial to crush your machine intentionally? I've read that YMN and DBS did so in their CKDF videos.
