Your point is interesting anyway. The fading you refer for the Tech prints (the most reliable references we have) would be the fading of the o-neg and of the IP before the print were struck (this is less thant one year AFAIK) ? And the fading would be only noticeable on the highlights ?

So, to go from a tech look to the original unfaded look (excepted the flaws of the printing process), the green channel should be pushed for the very high values ?

(no explosion in that example, so the difference is minimal)
