How can there be any doubt over when Hopkins's prime and peak were???

People are doubting when his prime was because he seems to come back smarter and wiser everytime. For me his absolute peak was probably the Trinidad fight, he was still physically good enough and that was when he was at his smartest [I still think he had things to learn after the Johnson fight, although I'll have to watch it again, he impressed me in Allen III aswell I think, again I'll have to watch that soon].
