Gary from BBInfinite recommends not filling more than 60% as there needs to be room for the grease to move about and so the bearings can actually roll. Not an engineer so don't know if this is true or not but can say that they are doing something correct with their pixie dust as their bottom brackets are the best I have used in 28 years and seem to survive our PNW wet, dust, mud drivetrain (and entire bike) destroying conditions.
