As someone who charges to 100% 4-5 days/week, every week, and commutes 240 miles for work -- Runt is correct, there is absolutely no need to baby/worry about the battery. I signed up for TeslaFi as soon as I got my car, so I've got all the stats for how the battery is handling things so far (I've put on 15k miles in 4.5 months!) and guess what? Overall there's been ZERO battery degradation. Last week it charged right up to 309 miles at 100%.
This fluctuates however, and it usually completes charging slightly below the 100% line at about ~306 miles. Fully charging and discharging, and then charging back to full, and then repeating this process a couple of times helps the battery cells balance/recalibrate. After doing this it charges right back up to ~310 miles. So, yeah... I wouldn't worry about it. Just drive your car and enjoy it as you would any other car.
