Pacifism Scoring Study

Here's what I found so far about the scoring system for the Pacifism game mode. (Yes, I play too much! My best score at the time of writing was of 502,159,825 points, hoping to get the billion one day :D)

M : Multiplier

  • Gate
    • Each end is worth 25 points, for a total of 50 points per gate
    • Each end spawns an orb, for a total of 2 orbs per gate
    • Score = (2 x 25) x M
  • Blue
    • Each blue spawns two orbs
    • Score if M is odd = (62.5 x M - 12.5)
    • Score if M is even = (62.5 x M)
    • So, score = (62.5 x M - 12.5 * (M Mod 2))
      • 1 : 50
      • 2 : 125
      • 3 : 175
      • 4 : 250
      • 5 : 300
      • 6 : 375
      • etc.
Example : If you're at 200 points with a multiplier of 9, and hit a gate that kills 3 blues, your score will be : 200 + (9 * 50) + 3 * (62.5 * 9 - 12.5) = 2300

What I'd like to determine now is what the following in-game tip means exactly:

"Crossing several gates in quick succession awards bonus points."

I know the sound is different when crossing gates in quick succession, but it will be hard to determine the actual bonus given, and when it stops being higher, if it ever stops.
