I've been highly doubtful about the Zeiss study that showed only 5% of people see RB. I think it's more accurate to say that a fair number of people do see RB (almost 1/3 by your estimate), but that only a small minority of people can't eventually adapt it to it. From reading posts over the past 5 years since the SV EL was introduced, it seems that a fair number of people reported seeing RB initially, particularly in the 8.5x model, but the majority of those people adapted to it after minutes, hours or days of use. Some of those who didn't, tried the 8x32 model and found it more suitable because of it having more pincushion. My effort has been to let people know exactly what it is they are seeing, and I've often pointed them to the technical reports on your Website for more thorough explanation. I have also let them know that the chances were in their favor that they would adapt to the RB over time, so they don't reject the bin or send it back w/out first giving themselves time to adjust. Even though I've gotten a lot of grief from the same few people for mentioning RB on BF, I think that educating bin users about RB is a better approach than simply saying that I don't see it, my wife doesn't see it, so it's a non-issue, don't worry about it. That's not helpful to the 30% who see RB but who don't know what it is and so don't buy the bin they otherwise like very much because they don't realize they need time to adapt. The best choice is an informed choice. What's confusing this, however, is the fact that Swaro has apparently tweaked the amount of pincushion in the 8.5x model such that newer samples may not be as low on your chart as the one you tested, which fell below the k=0.85 line. Recently, a BF member who had seen RB in the 8.5x model early on, tried a new sample and didn't see it. That's anecdotal, but when combined with what a Swaro rep told you about the company increasing the distortion in later production runs, it seems that Swaro has added more pincushion to the 8.5x model, or perhaps even its entire SV EL line. I wish you could get your hands on an old and new sample 8.5x SV EL to confirm this scientifically. The other thing that made me doubt the 5% figure in the Zeiss study was the statement by Zeiss (not sure if it was part of their SF advertising or if Mike Jensen posted it here), but the gist was that Zeiss purposely put in enough pincushion so that users would not experience RB with the SF (some still do as we have recently found out). So if only 5% of the population (or at least 5% of Zeiss's study group) see RB, then why would Zeiss purposely introduce enough pincushion to overcome the AMD? Seems like a lot of bother to cater to such a small group! Ditto for Swaro adding more pincushion to its SV ELs. Either that or I have such a BIG mouth that they would do anything to shut me up. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" />Brock</blockquote>
