To be fair/ kind to DPR, the K-1 AF settings are complex and perhaps a little poorly explained in the manual. Much the same as the K-3/K-3II AF settings.
Canon and Nikon give you 20 pages in the manual about their AF settings, have white papers about it etc. Even though it has just about the same level of features as Canikon AF, Pentax gives you just 2 pages in the manual about the K-1 AF, and one page on the camera web site about it.
