  2. RULE OF THUMB FOR FOCUS INTERPOLATION

    For the last scale before infinity, the interpolation is

    two times that number

    for exampe ...........4 infinity

    then interpolate 4 [8] infinity

    For the rest use linear interpolation is good enough
     
  3. The center between two points p1, p2

    = 2*p1 *p2/(p1+p2) is called the HARMONIC MEAN of these two points
