Not quite a large enough pool of numbers to draw any conclusions but I will anyway. If we round up to 226 and down to 228 for the L and regular P, 100% should yield 251 miles and 253 miles respectively. While the 90D would be 263.
When new, my P90D Model X was 225.
After 3 months and 2,000 miles it is now at 223.
Almost the same range as the 3 year old Model S P85 version "A" battery pack with 45,000 miles.
FWIW I am using the "most recent" report for those that have reported more than once. If you check in later with a different number I will update it in my spreadsheet.
