KJo was listed at the bottom of your “Swing + Open” range here, which encompassed about 13.5% of your hands. You probably should have included more low-to-mid pocket pairs in this range, which would put KJo as a marginal holding (occasional open, occasional fold) in a ~16% range.
As such, I’d look to open it when I’m two positions off the button, assuming everyone earlier had folded. That would leave four players left to act, two of whom would have position on me postflop, and two who would be out of position postflop. In earlier positions, or if players earlier to act had limped/raised, we should play tighter and fold KJo.
