Note, normalizing EG to a particular proportional split in the population may correct this. One possible Corrected EG (CEG) is (1±EG)/(1+IEG) - 1, where IEG is EG for the ideally proportioned case, as above. The sign used with EG depends on whether the wasted votes favor the majority party(+) or not(-). CEG = 0% for the ideally proportioned case, and CEG = 0.9/1.1 - 1 = -18.18% for the reverse case of the above, 10% EG against the majority party. North Carolina is a gerrymandered state with previously 3 Democrats registered for every 2 Republicans (~60/40 as above) but elects only 3 Democrat vs 10 Republican Congressmen. The NC CEG for 2016 is (1-0.1928)/1.1 - 1 = -26.62%, and for 2018 is (1-0.2746)/1.1 - 1 = -34.05%. EGs here are negative for the majority party wasted vote disadvantage. Reject a hypothesis of no gerrymander if |CEG| > something like 10%.
