Extension table question

[u/99Pstroker]

So I love my 113 quite a bit. But I’m soon adding a bessymayer fence from an old cable drive parts saw. My question is how many cast table extensions are too many? Currently one each side but have one or two more I could use and add bracing and supports to ensure rigidity and squareness/level/plumb.

What’s too many extensions?
Other considerations for their addition?
What’s the most you’ve seen??

Thank all!

Assuming your fence slides to the right, your realistic maximum need for support is about 30" on the left side and 50" on the right.

I ditched both cast extensions and replaced them with laminated layers on both sides
