MDF for flooring is horrendous and I would replace with OSB anyway. You have two options, use something slightly thinner and shim it to the right height. Or use something slightly thicker and route channels in the OSB where required to take it to the right height.

Circumference would be about 94" -- so a dozen to 15 would be plenty. I would calculate how many I wanted and even spacing for them (one per brick, two per brick, whatever) and then drill maybe half of them, light a fire and see how it burns.

On the other hand, you can't really have too many, so you can do them all at once if you want.

I'd get a small piece of plywood so you can lay the drill on it's side and just push, instead of having to hold it up.

We have a similar setup to what you have, in Ontario. We are now looking to add a gazebo or screen room on top of that deck, and we cannot get a permit unless the posts go down to frost level. If that is even a remote possibility in the future, save yourself the trouble and do it properly now. We wish we'd known that 10 years ago.

False, there are soils that are none frost susceptible (NFS) like dry gravel that don't heave.

In some soils a footing to the frost line isnt sufficient to prevent frost jacking. Where the freezing soil heaving lifts the footer out of the ground with friction along the sides instead of from heaving underneath.
