Yup, charging to 100% takes a LONG time. You should only charge just enough to get to your next destination. It will charge far faster on the low end vs the high.
44kw at what looks like 70% seems a little slow, but you would definitely not get anywhere closer to 100+ kw speed above 70%. Charge to 70%-80 and move on is usually the best tactic unless you need to range to make the next charging stop.
You started a supercharge at ~70%SOC, and are trying to get to 100%? That's not how it's done. Drive further / faster till you get to the next supercharger.
