I scrapped that entire testing procedure and started again as I decided it was too prone to non-repeatability errors. Waiting for some indeterminate period of time for the AS3 to settle/cure was giving me the proverbial .....
I retested using regular white goop, which yields about the same initial temperatures as AS3, but AS3 does gain over time as it cures.
Retesting and remounting the White Water and the Cascade 8 times so far in alternation to greatly reduce the chance of any single or even a short run of mounting errors from skewing results, I've come to the following results.
The Cascade use experimental base #1 is better than experimental base #2 and #3 by around 0.5C and 1.0C respectively. This is extremely promising as there's a pattern to the order of the bases and it gives me an idea of what is the right direction to be heading.
Compared to the White Water, Cascade base #1 is marginally (and I do mean marginal) better than the White Water. We're talking statistically inseparable given the limitations of my test setup, but if I had to pick one, I'd say the Cascade was ever so slightly ahead.
Using these results this gives me great insight on how I should move forwards to further refine the design.
There's still quite a number of things to do to tweak it to the max. The jet plate I'm presently using has some issues due to the material use and how it reacted after machining. The machinists have made a new jet plate out of a better machining-friendly polycarb, and this will help to fix some of the irregularities in the plate I'm presently using too.
Of course, it could be that there's very little left to gain. Only time and further refining will tell.
