You don't need to do a 2/1 or even a 3/1, in fact a very strong case can be made that it's sub optimal. So yes, I would say that you are potentially short changing yourself and limiting your development.
A better approach would be to increase to some workload, maintain that workload until you've adapted, then increase again.
Your training week should have lower training stress days built in to allow you to recover.
I often think that those advocating some sort of X/1 haven't gone through the literature in periodization and if they have, have failed to grasp what it really means.
