Hybrid Hamilton-Webster and the Greek apportionment

The method of largest remainders (Hamilton) is used for allotment of 288 of the seats among the 56 Greek constituencies. This method possesses various paradoxes as was observed through two centuries of application. So we propose a modification where the seats are allocated at a first stage by the lower Hare-Quota and the additional ones using the method of major fractions (Webster) restricted simultaneously by the upper quota. This method may produce paradoxes but they are observed extremely rare. Extended simulations over the Greek electoral data indicate that the frequency that the new method violates monotonicity is by far less than the frequency that Webster method violates quota.
