I realize you are saying these charts are not to be followed exactly, and that they are only a guide. However, it seems a quite unreliable guide. Look at the most recent example...... last year! THE LOWS for the entire calendar year were made on June 29th. Corn proceeded to rally $4.75 on the weekly chart.........$4.75!!! For decades corn often only rallied a dollar during most years.
A $4.75 rally!!!! At the exact time (June) the other 2 posts in this thread are implying that it is a given that corn DROPS every year.

This is the problem with "seasonal charts". They are inexact and general. People pull them out when they happen to match the current year in a very general manner.
