And, yes, I know that without assist, the engine + CVT combo in this car is a dog - I've experienced it. But I'm used to driving a 74 hp Mirage and 50 hp Metro/Firefly. It's all relative.
Coasting in N and disabling assist at will would be the ideal combination, but otherwise I see your point about just using the "engine braking" regen.

The CVT essentially isolates you from having any meaningful control over assist/regen.
Most hypermiling techniques are negated by the hybrid function. With a marginal battery, a 50/50 surface street/freeway commute and no A/C, I was able to consistently get 51-53mpg as follows:
- Limit surface street acceleration to 2000rpm. Highway: 2500-3000 depending on traffic.
- Punch it firm off the line to cause the assist to spike and then taper off at the rpm limit.
- Use "engine braking" as much as possible, brake early/gently to avoid binder use.
- Limit surface street speed to 42-44mph, highway to exactly 65mph.
That's it. Even with 1 forced recalibration per drive, I was able to maintain that mileage.
While terribly inefficient, you may want to force charge the battery to full. Simply hold rpm at 2500-3500 while in park while the car displays charge bars. Once complete, you'll have 8 bars of charge, and it won't charge at the high rpm idle.
Another option is to disconnect the 12V for 2 minutes, start and let car idle charge until it stops charging. Repeat a total of 3 times.
