Yes, another timing question!

No problem. Lots of good people on the site willing to assist.

You might see what the vacuum reading is at 22 or so initial compared to the 30 you got max reading. If it's close, within ~1", run the 22 initial and curve the rest in. I usually advance to max vacuum, then back off 1" for a safe margin. As long as it starts warm, you are usually good there.

You should be able to bump the key and it will fire right up with more initial.

The set an engine using total timing crew is another group that doesn't think initial is important. Don't get me wrong, you still need to find your total number for max power. Once you do it this way, setting initial, then tailoring for total and not just letting initial fall where it lands, you get a much more pleasant, less stinky and snappy car to drive. It's a little more work, but, MUCH better in the big scope of things.
