Zoro never used KOH. In 1094, his haki started leaking out and he called Lucci weak. In 1095, after sensing Saturn entering the island, he switched back to Nitoryu and logically has been fighting in base ever since.
It's clear that Zoro is saving his strength vs Lucci because he senses far stronger opponents on the island.
The only way Zoro could be using less strength against Lucci rn is if he stopped using haki all together. Meanwhile, Lucci is in his strongest form and the two are dead even. It's not looking good brev.
