About the SOC jump

The Bluetti charge jump, my term, i.e. when charging, a rapid move from less than full charge (say ~70%) to 100%, seems to be well documented and various solutions have been proposed, such as a couple of full discharge-recharge cycles to reset the unit. My question is, has anyone tested their unit after such a jump to see what the SOC actually is? Is it 70% or 100%?

Just curious.
