Limit To Amount of Animations for a Model??

What is the limit of animations a model can do in war3 or is there no limit?

The highest i've seen from the original models are around maybe 13.

For each animation, how much more memory space would the model take up for a 2 second animation?

I don't know about how much space it takes, but as far as I know you can have as many animations as you wish. Or it's some limit like 256 or a number like that, but more than you'll ever need anyway.
