Yes and yours is a more unique case. You had the FSD during that brief period where FSD was really prioritized. The large majority of MYLR orders being fulfilled right now are in the Oct and Nov threads with some Dec and still some Aug waiting. I've seen the occasional Jan/Feb/Mar but it is not the norm yet.
You are very lucky to have a MYLR order fulfilled in less than 4 months. There are people now getting estimates that will put them at the 1 year mark from when they ordered their MYLR. Even most MYP orders are being fulfilled at 3-4 month mark. And some of those people have FSD on their orders but that meant nothing back when they ordered and continues to give them no priority. Meanwhile it seems if people add FSD to their orders they are getting prioritized right away. Some October and November people have started to do this to get a VIN and it is working.
