ABRP + LeafSpy gives incorrect battery level

I am using the LeafSpy integration to get live data from my Nissan Leaf. However, LeafSpy calculates SoC differently than the car does - it reads 90% when the car reads 100% and 20% when the car reads 10%. This discrepancy carries over into ABRP and causes it to overestimate range, particularly when battery is low. If correcting this automatically isn’t possible, it would be nice to at least be able to manually set an offset scale to make the numbers match up with what the car shows.
