Lots of searching clues in that one.

Here is one discrepancy

Pr today The SAS-51's pressurized hull is composed of a combination of Tedlar and Mylar that effectively has reduced the helium diffusion rate to one liter per day.

Lotte brochure The laminate
of both foils leads to a permeability of
1,00 ltr of Helium per m² and 24h.

If they have reduced the helium diffusion rate to one liter per day for the complete ship, thats incredible.

Looks to me you can stay up a long time.

1 cubic meter = 1000 liters
1 CM lifts 1 kg
1kg = 2.2 lb

SAS-51 weighs 220 lb
100 CM lifts 220 lbs
If they lose 500 liters they only lose 1.1 lbs of lift.
