Be careful evaluating mounts PE based on a single example, especially for lower priced mounts where the QC can vary quite a bit. Watch out for ages of mounts in various comparisons, the link that Eric supplied being a good case in point. Older versions of many mounts have evolved over time, the vendors have made improvements as they've been sold. If you don't know the age of a mount in a comparison don't be too quick to dismiss it based on a large PE. Watch for folks who have "upgraded" or "tuned" a particular example of a mount. You can usually reduce the PE of a mount just by taking it apart, re lubricating it, and carefully reassembling it (in automotive terms this is similar to "blueprinting" an engine). Also take a close look at the type of PE. Large swings are one thing but a large amplitude PE that is very smooth (doesn't have any high frequency changes) is going to be much easier for an autoguider to handle than a mount with a lower amplitude PE but that also has a "rough" appearance (lots of sharp high frequency changes within the general graph). Yes, there are a lot more things to think about than just comparing a couple of numbers.

On the first link, they have the AP mounts with the least. And the G11 came in very respectfully.

I wonder if they made a mistake like entering the wrong params into the testing program.
