Yeah, I had a model S for about 4 years and struggled with the bottom 20%. Everything becomes a stressful game of can I make it if the wind is too high. Part of this issue will be solved with more charging stations but the other part is degradation as you said.

I can relate. I've gotten pretty confident by watching the *consumption tab -- but i don't think most drivers should have to .

I think the ones who dismiss this issue drive regular routes with the EV and don't push the boundaries . Then there are the rest of us who actually try to test the limits where you encounter a good deal of unsettling unpredictability .

I've pulled supercharger data and found discrepancies between the before and after kwh delivered -- explaining some discrepancies in the charging and forecasts. I don't think anyone else has gone into that level of detail.
