based on the Dale Clemens formula, as explained by
Art Port. This formula is also available in a
standprogram for MSWindows from Al Baldauski

The program requires three inputs,
in a choice of American or metric units:

The number of guides. A rule of thumb is to round the
length of the rod to whole feet (rounding up for six
inches), then add one. This gives the number of snake
and stripper guides, not counting the tiptop.

Distance of first guide from tip. In inches or
centimeters.

Distance of the butt (stripper) guide from the tip.
Generally, the stripper guide is placed about 25 inches
from the rod butt for averagelength rods, maybe more
or less for long or short rods or casters with longer or shorter reach.
