Hi Rico. This is the change in your workflow I am suggesting: half-press.
Each time you release the shutter button and press it again, your K-1 attempts to focus. If you are missing shots you should try holding your half press. When you fully depress the button an image is immediately taken without the focus system engaging. After the exposure is complete, return to a half press without letting the shutter release button come all the way up. As long as your subject isn't moving outside the pre-focused depth of field, you won't miss any more shots.
Another way to describe this technique makes sense if you have been trained to shoot semiautomatic handguns. I was used to competing in long-distance, single shot rifle events where you shoot once and remove your finger from the trigger. It took a lot of handgun training classes to get my hands used to pressing the trigger and releasing it until the trigger catches for the next shot. If you release the trigger all the way there is slack in the trigger take-up and finding where it catches either takes time, or causes a shooter to lose aim due to sloppy trigger pulls.
