Well, actually, after he measured the MOI of many British game guns, he said those with the center of balance within that range tended to be lively.
He didn't say that center of balance was the cause of the guns being lively. More of an indicator.
OK. But he should have known better than to try to use balance as an indicator of swing effort (MOI). It is actually a better indicator of weight which is a better indicator of swing effort. Thus we get far afield from the "question." It is far better to say, "This gun weighs X pounds, balances Y inches in front of the trigger, and I find it lively/numb/wand/club/2X4/etc." GT expended a lot of effort explaining gun handling to shooters who had little inclination to understand.
