Ed, the standard range (=cheapest) model 3 is listed with an optimistic range estimate of 220 mi so the available battery capacity is likely in the 50s kWh. Since this was a rental, the capacity has likely degraded from abuse but let's say it is still 50kWh. You charged from 9 to 80% so 71%, this means that the charging of a 50kWh pack should have been: 71% of 50kWh = 35.5 kWh so it is likely that the battery of that model 3 is deteriorated below 50 kWh or that the SoC estimation software is off, which is possible but unlikely. Driving distance depends on a lot of things, as you probably know. The terrain, ambient temp and especially the use of HVAC will all affect the range. If the available capacity is indeed deteriorated to ~45 kWh and the driving that you did is below the average 3 mi/kWh then a full battery will only give you half the rated range so closer to 110 mi instead of the optimal 220. Then, when you "super"charge to 80% and keep a minimum 20% buffer, your available range to drive around is about 60 miles which is consistent with your report. Hope this helps, Cor.
