Posting pictures is optional.
What people usually want to see in a picture is that the G's aren't too high and that the time is from 1/4 mile.
If I was to accept PM'd pictures as verification , people would still remain suspicious of "player x"'s time.
It is natural that people's first reaction to a new fastest time is : "Wow , really.. no way , he/she must be cheating / running 400m or has SRF on."
About tuning tricks (toe settings) , launching tricks and so on.. If it works for the offline dash , you can and should use it.
But don't come telling me it's cheating because it doesn't work online or real life.
Tuning out of others pictures.. ? I can't do it for starters
And I'm too stubborn to try to figure out something out of a picture. (0-60 and 0-100 times)
I find it easyer to just test 'n tune by myself.
Preferably everyone sees the pictures or noboby sees them. (No special treatments)
But let me ask you , why did you take pictures of your times in the first place if you didn't want people to see them?
