And here they are (only 2 cycles instead of 5 as promised, given the consistency of the results I decided they should be enough):

These measurements were done with my Enova Gyrfalcon S8000 as announced, and in case anyone’s curious, here’s the complete charger program I used for the tests:
INFO: Instrument IDN: ['ENOVA TECHNOLOGY', 'GYRFALCON S8000', '0000', '3.0.58']
slot_config: {'program_serialno': '1', 'battery_type': 'li-ion std', 'task': 'cycle', 'cycle_mode': 'cd',

'program_longname': 'CY?LIC>D5#', 'program_shortname': 'CYLIC>D5#'}
Given these results are not only pretty consistent among themselves, but also pretty much check with what @HKJ posted at the top of this topic, I’m calling “case closed” on this and considering (at least for the VTC6 currently being made by Murata) that a charge-termination current of 150mA is good enough for a full charge.
Next test will be done under more realistic conditions: they will be paired in 2S configuration and inserted into my friend’s Rekon35 drone (which takes 18650 batteries and whose manufacturer explicitly recommends the VTC6), and will be drained at 10A constant (or as constant as possible) to see how they perform. Since I answered my own original question (Re: the charge termination) and to avoid hijacking this thread even more than I already did, I will only post the results here if someone asks for it.
Thanks everyone for listening/reading and @HKJ specially for his prompt response to my question, and for posting his original results in the first place.
