Ok, can you guys give me a little math help?

1 capacity bar down and the obd/odb??? device I got didn't work with my phone...
Yesterday, I plugged into the DCQC (Chargepoint) and it said I was at 29% charge. However, the car said I was 'low battery' with 1 range bar left (plus the hidden 1 bar). I plugged into the DCQC and charged to ~35% which was 3 bars and got home with low battery just popping up.
Fast forward to today. Plugged into the 240 volt Chargepoint device at the office. Current (pardon pun) state is 'active charging' but it's drawing 0 Kw. I didn't set the 80% override to 100% so it should be at 80%.
The pack holds 24kWh right?
Only 22 are available to protect the top and the bottom?
20% degradation of 22 is 17 kWh right?
Charging to 80% of 17 = 13.6
Consumed 12.2 so the remaining 1kWh on the math should have been what was left in the car when I plugged it in right?
So how was the DCQC coming up with 29% when it looks like there was only around 1kWh in the pack with the low battery warning just starting?
Or did I miss something (entirely possible- history major not math major)?
