The 30 mm ball draws slightly more power as J increases from 11 to 16% but the gain in capacity is much more. In fact for an increase in J from 11 to 16% (i.e. 45% increase), power draw increase is 31%, while capacity increases by 51%. For the 50 mm balls the respective increase in power and capacity is 28% and 42%.
