Path Analysis results not consistent with page actions

I hope I am using the term "page actions" correctly. I interpret this to be equivalent to page views. In any event, I have created a few path analysis paths, using page values from some working goals. However, the results do not match. For example, I created a path analysis of the checkout path using urls from goals that I had created for each step in the checkout path. The goals log the customer actions but the path analysis does not. Selecting one completed customer order the path analysis does not show any actions beyond the first page in he path.
Also, the path analysis numbers do not match the page actions, or at least not consistently. I compared the visits to the first page in a path with the views of that page for a given day and in some cases there were no visits but the path analysis showed several, and in other cases there were several visits but the path analysis showed none. There are also instances where they both show some but the numbers do not match. It seems that things are not working right or I have it mis-configured, but I am not sure which. Is there any way to view the details behind each page in the path directly through the path analysis interface?
Any help or advice is much appreciated. I have several more sites, along with a significant increase in pages that I want to add to clicky but am reluctant to do so until I get a better handle on some of these functions, and the path analysis is a critical one.

Thank you.

Hi evcuser.

Our path analysis implementation *does* employ extrapolation, so the numbers are not guaranteed to be 100% accurate. This is a performance/accuracy trade-off that was made because of the size of our data set.

We've toyed with and considered allowing our users to interrogate the entirety of their data for a given date range, but at this time it's just not quick enough for higher volume sites.

Regarding viewing 'page details' right in the interface... it's one thing on a long list of improvements that we have planned for this feature over the coming months.

Thanks for your comments and some additional insight into how path analysis is being used in the wild.

Thank you for your response and additional information regarding the development and refinement of the path analysis function.
Since leaving this post I have done more testing and still believe that there is something more than an issue of extrapolation. I have a path analysis set up to show the checkout path from the initial shopping cart page to the thank you page. Though I have had plenty of orders that follow the exact path since I created the path analysis, there are not any being completed in the path analysis. All are dropping off at the second step in path analysis.

Thank you,

Is there any update to this? I just set up a path analysis on one of my websites to track visitors from the time they place an item in a shopping cart to when they reach the Thank You Page. In all there are four pages being tracked. It is saying that there have been 3 visits to the Thank You Page today, however there are no orders - and my goals page does not show anyone hitting the "Thank You" page.

How exactly is Path Analysis set-up?
