The bold part is not true though, right? (please don't take this the wrong way; I'm not trying to call you out and I appreciate all the great information you always share! I'm simply trying to figure out what I want to do with my new MY in regards to tint and been doing a lot of research -- and I keep seeing conflicting information).
According to the video linked on the first page in this thread (around 1 minute in) and other similar videos, people have measured UVR/IRR/VLT of the factory windows and, untreated/not tinted, the factory front side windows clock in around ~75-77% IRR with the rear side windows showing around ~90% IRR. Are these measurements incorrect or is there something I'm missing when it comes to factory windows on new MYs? It feels like half the posts I'm reading are of the "rear glass is just dyed and front is just dual paned with no UV/IR rejection" variety while the other half quote measurements or do their own and show there's quite a bit of UVR/IRR -- one can argue it may not be enough/you'd want more/etc. but that's a different story.
