An early Compur that I serviced has a time delay in place of a press to focus. With the lever tab next to the speed dial is normal operation, pressed toward the rear of the shutter is full delay. It should not be in between the two extremes.
Speeds above 1/100 are acieved by a booster spring that is compressed when the speed dial is turned to those speeds. It is normal for the speed dial to be harder to turn to the speeds above 1/100.
