My experiences have simply been different. I've been in conditions several times in legal hours where I would not have felt comfortable taking a shot with the Leupold I was using and even once with an IOR (reticle got hard to see) where I would have been OK with a different IOR or the S&B I now have.
When comparing all these side by side as it gets dark they do not all cease to work at the exact same moment. Some last longer than others. Usually, they all last beyond legal light, but not always.
