My 2017 X 75D also shows 228 miles for 100% charge, and I have supercharged only 6 times since I purchased the car. thats just over 4% degradation for 19000 miles. Is that fairly typical? Does it get worse?

Thinking about what I would have done, I had a hard stop defined at $100K. So if the extra $6K would have pushed me over that, I would not have done it. If it was at or under, I would have done the upgrade.
I ordered a 60D instead of a 75D because I had to get the 6 seat and air suspension in order to get delivery in 2016. To offset that extra cost I dropped from 75 to 60. Eventually the price to upgrade to 75 dropped to $4500 and I did that via web site. Total was still under $100K.
I charged to 100% last week and the range on my Dec 2016 X was 231. 2.5% reduction over two years doesn't seem bad. I charge to 90% at home each night. Only a few supercharger stops.

When we spoke with a Tesla sales manager on Saturday, he said the extended range can be added at any time up until delivery. He said it was similar to the 60/75 upgrade option. Since it is a software lock, I'm certain they will be willing to offer an upgrade after delivery.
Is that calculated using a 100-10% run or just relying on the BMS 'guessing' charge state?
Roughly 10K miles ago, our 'regular' 150 mile trip to see in-laws, 100-12% for trip, car reported 59kWh used = 67kWh 100-0% excluding any unreported buffers/reserve.
Now car is at nearly 19K, same trip, almost identical temp, 100-11% for trip, car reported 59kWh used = 66kWh 100-0%.
So in 10K the degradation is 1kWh at the most, or about 1-2% if you assumer 67kWh usable.

That's alot higher degradation am seeing in our 75D X. I don't expect ours to be above 5% until near 100k.
The thing that would put me off this upgrade is carrying around 150 kg of extra battery I couldn't make full use of. That and the extra cost! It sounds like you are paying $6K to effectively carry a 150 kg dead weight. Fair enough if you actually needed the slight increase in range or faster charging (at Superchargers only) but for me the 75D is already a heavy enough beast as it is. Given your driving routine I would probably save the money and take another holiday or treat yourself to a $6k spending spree!

What state are you in? If it gets cold in the winter you should factor in the significant range loss if you're not pre heating daily. If a warm state you may not need the extra capacity .
