Tesla's rated range is based off of EPA validation which takes into consideration real world condition, if EPA estimates 294 thats the number Tesla uses. The Ideal range is the Optimistic number that does not factor in real world conditions so it might say 310+ miles. However, to your question your max or daily charge max will vary based on weather. If you received your car in the fall/winter temperatures you can expect your MAX to go up a bit as weather gets warmer, but typically by 1-5 miles depending on your pack. Historically, it seems that the pack needs to calibrate and would often show a much higher number when new e.g. P/S85's used to show up to 274 miles of range when new and fully charged, but calibrated eventually to 265 per the EPA number. So it will vary per pack and based on how new it is and weather.
