Distance per Hill (\( Dph \)):

\[ Dph = \frac{S_r \times \pi \times D_g}{N_c} \]

Where:

• \( Dph \) is the distance per hill, in millimeters (mm).
• \( S_r \) is the speed ratio of the ground wheel and seed plate.
• \( D_g \) is the diameter of the ground wheel, in millimeters (mm).
• \( N_c \) is the number of cells in the seed plate.
