Yes! and that -19 offset is interesting.. Looks like you need to knock about 11Ah off the Ah capacity in order for it scale linearly with the health. Notice on the graph the health highs and lows are higher and lower than the Ah capacity..
Cap vs health:
Perhaps health is a percentage of original USEABLE capacity? Since we can't really touch the top or bottom few percent SOC... Perhaps this is a better mark of capacity loss as it might better reflect loss in range?
