stock tint

i know we've talked of tint on here and whats legal, but what is the stock tint on the rear doors and back of an 07 DC?

 

i was wondering b/c i've seen conflicting stories everywhere. dont kill me or ban me people...lol...but i was looking on customtacos.com and even there i was 28%, 22%, and someone even said 13%. i ordered some tint off ebay and they said that the 20% most closely matches the others...just sondering since i've seen so many different things

EDIT: if you look at the table on this link, it says that the visible light on the CH 20 tint is 22%. that would kinda match the thread on the other site where the guy said he had a meter hooked to it and it read 22%. i think i'm starting to spazz over nothing. i'll post pics after i get it and get it done...whenever that'll be...lol
