I think you are simply learning that getting the $#&@ing shot in the first place, and getting it in focus, counts for a lot more than the shot's technical details in terms of sharpness, grain, etc. IME, it's consideration number one of picking a camera for a specific purpose. IMO, if you cannot get what you want with medium format, get rid of it, or use it for more suitable subjects. A camera is worse than useless if working with it is causing you to miss timing and focus. There is nothing more frustrating than knowing exactly what you want to focus on and exactly when you want to click the shutter, but stumbling over the camera and missing it.
