The RG calls for a .0024" spring for the 1000 day, and a .0023" for the 400 days.
Interesting. I guess there's a lot to understand about suspension springs. If I read correctly, two different springs are needed for essentially the same weight pendulum. Maybe it has to do with the location of the weight for each pendulum. Different rotational inertia...same weight but different distance from the center of rotation.
