Drop Scale Factor (DSF)

This allows you to enter and maintain a table of drop

scale factors (DSF) that utilize observed drop at range

to calibrate the elevation computation. The number

shown to the top right of the screen represents the

suggested range distance at which to apply a drop scale

factor for transonic ight. Additional drop scale factors

can be added to the DSF table by shooting at greater

distances including subsonic ight. Attempting to enter

an additional drop scale factor that is closer in range

distance than existing DSF table entries will invalidate

and erase the existing entries.
