I do believe the best way is to avoid the double lynch unless we are almost certain that between the 2 there's one assassin and we are not near parity.
*( ex. 2 persons claim to be the sage and make accusations against each of them, better to kill the 2, anyway the real sage is in danger to be killed next night since he revealed himself. ) *
Unless that, we should try to slow down the pace on the lynch, 1 per day is fine, to help us gather proofs and to give a chance to the non-assassin specialized diplomats to do their jobs.
