That seems to still be up in the air, as does a points system and quite a few other things that are vital to it actually working.So six Test series, three home and three away, from nine nations to qualify for the Test Championship. Is there a formula to which six teams you play or is it designed to increase games against the weakest teams in order to qualify?
I imagine points earned home and away will carry over between cycles, maybe to a maximum of six years or something; so eventually the points will from the latest result of all 16 combinations (8 home, 8 away) assuming they were played within the carry-over period. But that's speculation, there appears to be no detail.
