Yeah I was glad to.

FWIW if you go into the wood section with the select wooden boards, there are some smaller 3/8" thick boards I found and used my miter saw to cut some 45* into them and then use that as a guide to cut on. The 3/8" thick seemed to be perfect for standoff as well. I originally had 1/2" thick and it burned up an electrode pretty quick.

Also yeah I have seen with the post flow for extra cooling. My cuts were only 2" in 11 gauge and plenty of time in between them so the post flow didn't seem like it was needed as much for me. If i was going thicker I would deffinately turn up the post flow.
