Agreed, a wet manifold has fuel in the runners, always. On decel, the high vacuum (low MAP) boils the fuel off the walls, enriching whatever air is there. Solutions are varied, but include leaner decel area fueling of course. A problem is decel from 50%, 80% or 100% throttle reacts differently, so a compromise balance is tuned. Alternatively on road cars with long decel events, decel fuel cut can be used to allow the excess fuel to purge, and restart the engine at 2x to 3x idle rpm generally works well. You likely do not have that option, or it will be limited; but mentioning it as a perspective of decel tuning. You may want to add some
Idle Timing Control or a timing trough to your Spark table to help in decel idle recovery.

I still don't understand why readjusting the distributor would have any impact on the timing when I'm reseting back to TDC each time. I'm going to take the W for now and move on. 
It's not the cap, but the position of the pickup (sensor) that is the focus. You got there, and yes, move on.

At startup I get:
RPM = Oscilates between 530 and 730 for the first 10 seconds, settles at 650 and then slowly climbs to 720 after 80 seconds
AFR = 16 then slowly drifts down to 14 after 80 seconds or so
CLT = 68
Is this attributable to having no ASE? Would having ASE for 10 seconds at startup help to reduce the oscillation in RPM and improve AFR? Is the 650 rpm between 10 and 80 seconds just something I have to live with? I feel that I can't add much warmup enrichment because 68 is pretty much operating temp. If I add more to the VE or increase idle pulse width I'll be even richer and have and even higher idle after heavier throttle use.
Yes, you are confusing operating settings with startup settings. ASE is only short-term to stabilize Lambda, so you don't get lean surging (the effect you're seeing). The issue is that the tune is properly set for warm parts that vaporize fuel near 100%. Only vaporized fuel can burn. When cold, a smaller percentage of fuel vaporizes, and the rest can't burn. We see enleanment in the logs. To correct this, we add fuel, to re-gain that good idle Lambda.
The VE Table should be correct for normal warm operation, and left there. If the logs or data show lean on cold start, then add only the fuel for the time and conditions to correct those 'abnormal' low-vaporization conditions. Remember, tune warm restart first as your baseline (priming, ASE, warmup), which should be minimal, nearly zero, and zero added fuel.
For cold start tuning, I allow the O2 to warm and begin stable reading, then log a normal start. I do not cold-start with a hot sensor except for tuning that area. Following the log indications (which will read lean until it fires), I add cranking fuel to get quick firing and rapid swing to peak-torque Lambda (found in warm idle tuning).
Yours is looking fairly good with only 1s of cranking at that temperature.
Follow warmup progress, adjusting WUE cells along the way to full-warm. Extend the WUE curve trends for colder and warmer conditions. This should all be fairly clear in your cold start logs. Apply some predictive values from the log indications, and do it again when cold again, to find any bumps or wiggles in the series of corrections.
ASE is a startup transition "gap-filler" when intake parts and chambers are dead-cold and fuel does not want to vaporize well. If it starts quick and has a reasonable WUE, but goes lean between the two for some seconds, then add ASE to maintain AFR and stable run with as much fuel and as long as indicated to transition that startup-to-WUE gap when parts are cold.

Once I'm done I'll post up all my CAD files, tune files and shopping lists for anyone else crazy enough to want to repeat my process. 
We have a lot of crazy people here, and I'm sure some that will appreciate your efforts.
Once again, thank you so much to everyone that got me this far!! Hopefully I can enjoy this baby for a few weeks and then pass it on to someone else who will enjoy this boat as much as I do.
