A "standard" wall plug (i.e. 120V, 15A, which is actually 12A continuous) charges at 5-6 miles of range per hour for a Model 3. You don't get 11mph of charge unless you use a 240V-15A outlet. The 11mph you quoted assumes a 240V outlet. In practice, as you state, even with 5mph of range, taking multiple days to charge isn't actually an issue since you aren't fully filling up your car from empty every day.
