Steve,
Sorry for the late reply. The first thing you need to do is to determine if the Swarovski chart is sized properly. Group 0, Element 1 should be made of bars and spaces that are each exactly 0.5mm wide, so that the 3 bars will align perfectly with the millimeter marks on a ruler. The print quality of paper charts can be so poor that reliable measurements may only be possible down to Group 2 or even Group 1. Resolved with this chart means the smallest Group/Element that still allows the direction of the lines to be detected. The next smaller Element will look like a gray square.
The Edmund Optics table below converts Groups and Elements to line pairs per mm. Edmund used to supply an odd formula for converting LP/mm to arc seconds of resolution, which I still use. It works like this: Measure the distance from the scope objective to the chart in inches. Determine the smallest Group/Element resolvable on the chart and convert to LP/mm. Multiply the distance to the chart in inches by the LP/mm resolution. Divide 8121 by that number. The result is the resolution in arc seconds.
Here's an example; distance to chart = 1000 inches, smallest resolvable Group/Element = 2/1, 1000 x 4.00 = 4000, 8121/4000 = 2.03 arc seconds
Edit: If you want to stay in the metric system just measure the distance in centimeters and use 20,627 instead of 8121.
The experiences of Binomania, Frank and your reviewer are perfect examples of why resolution measurements and star-tests are so essential for reviewing scopes. Subjective impressions of sharpness are not reliable since every telescope eventually loses sharpness at some magnification. Whether that magnification is lower than it should be for a given aperture can only be determined by measuring the resolution and comparing it to the diffraction limit for the aperture. If the Kowa scopes had been star-tested we would know exactly which ones were defective and what was wrong with them.
