I decided to give Kringing another try, and once again got less than stellar results.
The results are very dependent on the settings, and different setting can give wildly different results. Since I only want to extend things 3', the grid-based option works very poorly, unless the grid spacing is set EXTREMELY small. Random Points gives much better results, but the surface does not extend all the way to my selected boundary; it only encompasses the random points themselves, which means the surface stops short of my desired boundary in most places. So the Random Points option is out.
I couldn't figure out how to get "Centroids" or "Edge Midpoints" to work for this task.
So it's starting to look like I can use Kringing if I use the Grid method, and use a very small value for the grid size, and let it generate a ton of extra points. Otherwise, it seems the best option is to ignore Kringing, and go back to the manual method I was using before. I actually get better results that way, too, even though it's not as "cool" as Kringing.
