Here you can create your gravity formula by entering angles/tilt and the corresponding gravity (SG). These values will be saved for future use. Angles with 0 (zero) will be skipped. The values below will be used to check the formula and if the deviation is more than 1.5 SG then the forumla will be rejected. On the bottom of the page you can see a graph over the entered values + values calcualated by the formula.
