Ok so they put this speed sign around my area, but the only sucking part is that there are 2 big and 2 mini hills between it. So i finnally tested it with behind the tint and under the rvm to see if my tint reduces anything. I took 5 total runs
1st run when v1 placed under rvm alerted 3 secongs early
2nd run I placed the b1 behind tint it alerted 3 seconds late the usally spot of 1st run
3rd run was behind tint agian and it alerted at the same spot when I did 1st run with v1 being under v1
4th run was still v1 behind tint and it alearted at the same spot agian as the 1st and 5th run,
5th run v1 placed under rvm and it alearted at the same spot as 2,3,and 4 when v1 was behind tint.
So i assuem my tint doest reduce tint, accept the 2nd run it was 3 seconds late, but the other runs it was the same. The signal kept going away because of the hills. I was going to do more runs but the people started to get suspicous of me that I kept driving around so I just left withouth getting introuble
