A taper - (Curry)rcurry

The following taper is from a no-name rod that has been refinished by many 
hands. The is an 8'3", 3/2, 5wt., Calcutta cane rod, with stainless-steel 
ferrules, and a delightful, truly unique, parabolic action. 

Both tips are 32.375" long. Mid and butt are 35.375" long.
Varnish thickness (total) probably .004", measurements are as read.
The following taper is in 5" increments because I'm so courteous and that's 
the demented method of choice.:) Please someone explain to me why five 
inches?? Is this something Freudian about Garrison that I really don't want 
to know?
