I defer to your greater knowledge in this area. My use of what little Gann I understand is more an adjuct than a determinate.
However, These time frames do work far more than chance would dictate.
One only has to look at the last year.
After a top on 21/03 we had a top on 20/06; 90 days.
A top 21/11; 8 months.
Bottom 21/10 to top 21/11; 30 days.
Etc.
