Falls within +/- 2% like I mentioned. I did each three times in different areas and consistently got the same reading. My intention was to average the readings but all three on each window gave the same result. May be worth noting that I took the readings with the truck in my dark garage to...
In case anyone is interested, below is the visible light transmittance levels of all of the windows of the Cybertruck used with a calibrated VLT tool within +/- 2%:
Front windshield: 76%
Windshield strip: 1% tapered to 76%
Front side windows: 72%
Front A pillar triangles: 72%
Rear side windows...
