To Vacuum Advance or Not to Vacuum Advance

At the top, I think I'd feel Ok with glancing at it.
Its at the starting line I know I wouldn't.

If I had a safe place to launch it like at the track, with lots of room, it would be interesting to watch the mechanical gage in the dash.
I think the MAP response is slow. Maybe because its electronic device, maybe because mine is on a long small plastic line through the firewall to the logger.
I agree about vac dropping. It seems to me vac drops pretty immediately with throttle opening, but maybe that's just my perceptions.
