For the sceptics - if you put preservative in a hole in the middle of the
post, where do you think it goes if it doesn't soak into the wood?

Out the cracks in the wood and just evaporate out of the hole.

Sure, it won't do a good job of protecting the outside of the post

Which is the only part of the post that matters decay wise.

that will be the bit the 1 minute pressure treatment did. And if the
outside rots away leaving a solid core

That won't happen either.

- well, that's better than the
outside and the inside rotting...
