Effect Size problem

Hey all!

Ive been having a bit of a hunt around on the forum, but im pretty sure my problem isn't so much a problem as just a way the Effects engine works..

My problem is that when i set my Begin and End parameters to 0% and 400% respectively, the Size param sets to 200%.

I record the effect and when I go to run the effect The Begin and End Params are at -200% and 200%..

Is their a work around to this or is that just something ill have to put up with?

Many Thanks,

Callum
