Before you backtrack...
If you think within a few years that you changed the Rut dates by a week on a specific piece of property.... this would be some groundbreaking stuff that nobody has ever achieved anywhere else that I have ever heard of in the wild.
Appears this is what you are suggesting.
Better let everyone else know you've figured out what to do. There is going to be a LOT of hunters interested in this and you've allegedly got a Biology Degree so they'll likely believe you.
And you would be 100% wrong.
