That's way too high. Zesshi is a "god-kin" and speculated to be a descendant of the Six Great Gods. If we assume SGG's level to be 100 then a difference of 10 for a god-kin is a minimum requirement. That means Zetsumei's level cannot go above level 90. I wouldn't be surprised if the difference in level is 20 because she's only part-God.

We also can't include her Divine equipment. This chart only shows a character's base level. If we include equiments, it wouldn't be an understatement that Ainz could surpass level 120 with full body equipment.

As for the captain, I'm not really sure if it was simply "above Solution's strength" or "much stronger than Solution" since you and another statement are different. The former would fit the value currently written on the chart but the latter could rise as far as level 70. I'm planning to read that part again to decide it once and for all but a day or two.
