Tespia is now OPEN!

Hey look. Exactly what I said!
2149*.6 = 1289
1289 * 1.5 = 1934

How about that?!?

Except that the .6 part is assumption and is only true in this case because the party is 2 people of equal level. The 1.5, you are right about. The ratio, you are dead wrong. I wrote a calculator yesterday that proves the ratio. I'll post a link to it when my cpanel account gets unlocked on my spare website.

60:40 is Chaos. 20:80 is Ascension (Tespia version).

Here is a temporary link for it -

Here is the Exp distribution using my testing scenario if the ratio is 20:80. These numbers match my results in Tespia.

Here is the Exp distribution using my testing scenario if the ratio is 60:40 as you claim. These numbers do not match, but they do match what you would see in Chaos.

EDIT: I have been looking through old threads on Jump and everyone wants to call the Jump ratio 60/40. Nobody ever proves the numbers, though. Unless 60/40 refer to different source numbers, it simply cannot be correct.
