I was wondering if somebody really needed it, if that person could change locations mid training for certain reasons?
Anything is possible. You’d need a valid reason and also it would be best if you did it at a natural break in your training (like in between ratings).
While possible, I would strongly urge you to avoid changing locations. The program just isn’t that long to begin with. If you start throwing in moving days and all the street that goes with it, it can definitely stretch things out.
