Those tests are based upon a 35mm 6mp sensor monochrome astro sensor. I think they are suspect. How can we know focus was perfect with each one with no live view? I think the 67 lenses should do a little better here. They might not be enough for a 36mp sensor, but they should be resolving more than 6mp on FF. If you extrapolate and enlarge the area to cover 6x7 that would indicate they are resolving less than 12mp if you had a 6x7 sensor since 35mm has a 2x crop factor.
