So I tested my charger today with my clamp on ammeter and from 50% to 91% SOC it was always pulling ~27.5 amps the entire time. I was expecting to see a several amp drop but alas there was none.

My 2016 ramps down at ~80%. I have a 32 amp ChargePoint and the charger’s graph shows a pretty steep decline that looks to start at around 80%. If you were using a 16 amp charger you wouldn’t see it until later.
You sure it's happening at 80% on the dash display? On my current and former '13 (obviously only 24 kWh), the L2 ramp down never happens until the car's in the 90ish% on the dash display... more like 94+%.
I've plugged in plenty of other Leafs at work, including '18+ Leafs (we have some of every model year) and I've observed similar behavior of not much energy making it into the battery in the last hour or so due to ramp down and bounces. See viewtopic.php?p=521788#p521788
for an example.
Here was one of my graphs of this. Took me awhile to find it: viewtopic.php?p=490435#p490435
At work, we have 30 amp EVSEs and our supply voltage is around 208 volts. Next time you can see the ramp down, power up your car and look at the dash display's % SoC. I can almost guarantee you that it'll be above 90%.
If I turn on my 80% limiter via midnight to midnight 80% timer (yes, it's gone on US '14+ Leafs), let it charge to 80%, it's full power the whole time until the abrupt drop at 80%. If I then via NissanConenct/Carwings app tell it to charge now, it'll charge at full power for at least 30 maybe 30 to 45 minutes before beginning ramping down followed by the 2 or 3 bounces.
