I can't measure it that way, but I'm pretty sure I'm getting no more than the 1/2" described above (and it is a Logic fork). Maybe I just never paid attention to it before the crash, and am now paranoid over everything because I don't want to crash again. That's why I replaced the fork, the carbon one got lacerated by the spokes of a collapsing wheel and although the fork did not break, it's questionable as to what the lashing did to it.
Steel is wonderful stuff. It can flex like that for decades.
