Another timing curve question

Today I hooked up the timing light again... turns out I had slightly underestimated the amount that the superlight spring advanced before the heavy loop engaged. So there was hardly any advance left because the FBO plate was hitting the stops at 18.
I experimented by removing the plate entirely (26 degree slots in the dist). And it works just about perfectly... idles at 27, starts slowly advancing at (estimate by ear) 1800, up to 35 by 4000, and I didn't rev it any higher. Thought it was screaming but the tach recall said not.
The ported vac advance doesn't kick in immediately as the throttle is gradually opened (I think AJ expounded on this in a different thread). My can is an "8L" i.e. 16 deg max, and I got just about to 50 revving it unloaded (17-18" vac.) May try it with full manifold, since my idle vac (8") won't pull the can in anyway.
So my timing may be pretty close, and I can always retard it a couple degrees from the dash (0-15 degree knob at my fingertips) if it's too much on the high end... May not have to send it off to @halifaxhops or YR :)
Now to get back to tweaking that crotchety 2-corner-idle carb since I've altered the timing!
