[Pre-BB] MapleStory Formula Compilation

I'd like to submit that the newest chain lightning multiplier is 0.7 as concluded from these images provided by BombsAway:

Her Stats:
Level 28 CL
Max Amp
677 INT
+159 MATK
No elemental wand or Maple Warrior

For quick reference:
IMAGE #1 - 11380 / 8855
IMAGE #2 - 11031 / 8857 / 5???
IMAGE #3 - 12566 / 8715 / 5768
IMAGE #4 - 12959 / 8??? / 5594 / 3533
IMAGE #5 - 12545 / 9290

So here are the calculations for Chain Lightning assuming a neutral target and all of BombsAway's stats:



0.5 Multiplier - Clearly ruled out by Image #1 on the second mob hit (8855 observed vs. 6709 max calculated). This multiplier is actually ruled out by all five images.




0.6 Multiplier - Again, ruled out by Image #1 on the second mob hit (8855 observed vs. 8051 max calculated). Also this multiplier is still ruled out by at least four images.




0.66 Multiplier - Clearly ruled out by Image #5 on the second mob hit (9290 observed vs. 8856 max calculated)




0.75 Multiplier - The calculations are too high. Ruled out by Image #4 with 3533 observed on the fourth mob hit (versus 4330 minimum calculated) and 5594 observed on the third mob hit (versus 5774 minimum calculated)


So, it is proven with certainty that the multiplier must be between 0.66 and 0.75. The only obvious multiplier remaining is 0.7. This multiplier fits with all of the images, and therefore is my submitted value.
