Yes, but it is quite apparent to anyone with internet access and common sense that they are completely washed out by the number of "LPSG" measurement pictures, and as I've said, when you get past a certain size range, they get rare as hen's teeth because everyone needs to live up to the bullshit numbers we associate with huge dicks. I have indeed seen a couple 90° standing ruler shots which were still up in that range, but I can't point you to any specific one and they show up very infrequently. You yourself may even have posted one, but I don't save (or remember) everything. They also most likely were not reaching the sort of numbers the top tier angledicks are known for, but ironically may have been larger in real inches.
Every technique you insist is still valid and doesn't "add anything" has been explained in detail too many times, often with pictures. If it really didn't matter, it wouldn't show up as much as it does, and you'd have no problem getting any one of them to do a simple clear measurement. Would you accept someone's height measurement in a photo which was taken from a tree branch three feet over their head and hanging two feet in front of where they were standing? The problems are obvious and we all know it just doesn't work that way. How accurate is a dick measurement taken from the bottom of the guy's shaft while laying down with his dick flat on his gut? Who the hell knows. How far down is he allowed to start measuring? His balls? His ass? How different is that really from the flipside scenario with the guy leaning back or angling his dick forward?
