Seams reasonable. It is rare though that the NLGI grade is sufficient for selecting a grease. I have been experimenting with relativery thin full synthetic gearoil (and ATF oil) similar to the official shimano mineral oil maintenance set mixed with a bit of the Shimano IGH grease. And then with synthtetic calcium sulfonate-complex grease for the bearings and coaster brake. Provides a litte more drag on the bigger righ-hand side bearing. But seems to work fine in temperatures down to -15 and up to +25 celcius and with heavy rainfall. With the added benefit of the increased wather protection..
