How did you get a plain dumb charger to cut back that far?
It's called electrical theory. Even the dumbest of dumb chargers have
to abide by it.
The dumbest of dumb chargers use rectified sine waves. Without a
voltage regulator, the state of charge will have little effect on current.

Really? The state of charge has a direct effect on the output of the
charger. Just what world do you live in?

You're talking about capacitors. If you charged a capacitor with a
regulated 1.4V, the current would taper toward nothing at 1.4. With an
unregulated charger, current would taper toward nothing at about 2V.

Chemical batteries are different. Voltage-regulated chargers have been
used for lead-acid batteries but never worked for nickel batteries.
Terminal voltage on NiMH drops when it's fully charged, which means a
voltage-regulated or unregulated charger would speed up.
