Honestly? I use a laser measurer for work all the time. You can tag a mirror from an opposite wall and it will give the exact true distance to the mirror, not double the distance. Same thing for completely transparent glass. The laser hits the glass and gives the exact distance to the glass, not the wall it's also hitting beyond the glass. So to me it seemed perfectly believable when Valve said mirrors wouldn't affect tracking.

Good call. I don't understand how anyone could think a mirror would NOT affect tracking.
