Even to get it to 85%-90% until they have home charging will be fine. I wouldn't worry too much about calibrating the battery. I think all Tesla means by that is that it would get less accurate on charge level over time if you never did charge it to full. I really wouldn't bother about getting it to full charge until it can be done at home. I doubt it would be a big issue, but I'd soak up that free charging while available. As fast as supercharging is 10-15 minutes at a time when it's at lower charge levels goes a long way.
The way I hear it, some drivers have run out of juice at 5% because the BMS had overestimated the capacity. And battery capacity is always an estimate. It’s really weird on computers where the estimated capacity can be sampled and I’ve seen it go up and down.
