Elaboration to help you understand why resting voltages and pack SoC as-removed vs. as-installed doesn't matter much.

The pack monitors 11 voltages: 1 total and 10 stick pairs. It also monitors current.

When assisting, for a given current, the voltages must remain above minimums. These voltages vary with current. When regenerating, for a given current, the voltages must remain below maximums. SoC is computed based on this range of operation and iteratively adjusted. It doesn't mean a lot.

At the end of a positive recal, 100% SoC indicates ONE of the 11 voltages hit max at the charge current.

At the end of a negative recal, 0% or near 0% SoC indicates ONE of the 11 voltages hit min at a given discharge current. Additionally, if any of the 10 stick-pairs deviate by 1.2 volts at any time, it triggers a recal. As long as your stick pairs are within 1.2V, they really don't matter.
