Hi Henrik!
Thank you and I finally got that the duty cycle is a "fixed" number assumed to be at 50%. According to the information about the device, each device can have a zero duty cycle of from 48.7% to 51.3%. My experience has been that at a room temperature of about 72 degrees F, my device has a measured duty cycle of 49.93%. However as the room temperature increase or decrease so does the zero point duty cycle! So if the submarine is sitting on a table at the park with an air temperature of 72 degrees F then 4993 works. Put the sub in water where the water temperature is 65 degrees F and 4993 is no longer valid. Originally the thinking was to measure and calculate the duty cycle however this method does not work as you first must be at an known zero degrees of tilt.

Best Wishes, Ed
