Whatever makes it play the best to you.

I don't know if there is a standard. On all mine i just experiment till it's right.

3.5 is suggested standard. I run mine about 6

I think this is what my Big Indian manual says. I run it about 4.5ish. Like any table, if its too steep it loses the side to side action. I originally had it about 6, but it just wasn't fun...faster, but lost all the finesse.

For EM games:

I use 2" levelers on the front and usually set them in all the way.

I use 3" levelers on the rear and usually set them screwed out about 75%.

Now that I think about it this is about the same set up I put on my DMD games also.
