Well that because Zanpakuto run off a base of 100% split between offense, defense and support. we have only seen him using it offensively hence the 75& and once twice for defense thus 75 - 5. We dont know enough to know if its more for one area or another fully so therefore 100 was not fully used. As for Shunsui's hakuda was being generous there is virtually no canon content that can really determine his level as being high. As for unohana her background is swordfighiting which has nothing to do with hand to hand combat hence why most captains arent on the lvl of yoruichi and sui-feng.
