Possable Formula Change for Double Exp Weekend!!

I have a friend on my msn who is now a pmod.
I was talking to him and we started talking about the double exp weekend.

He said that most/all the pmods and jmods are furious about it (I didn't ask why).

He said that the formula MIGHT be changing :O
He didn't actually say it will, he said it might.

 

I would think so, even the Forum thread by the J Mod mentioned new changes to teh event based on feedback.

Summoning is already capped. So more limitations will follow

 

Last time the 2.7x only lasted for 15 minutes instead of the 45 it was supposed to. They could be talking about changing that or a whole new formula altogether.

Edit: Here's the new formula: http://services.runescape.com/m=news/bonus-xp-weekend---3rd-to-6th-september

 

Probably a faster decreasing experience rate time?
