I don’t know, I haven’t tried that. I might, though.
I use the doorway into our bedroom/Temple sometimes because it’s otherwise always kept closed, and I think this works best with doorways that are closed most of the time (as they used to be more in the past, the days before central heating etc.) and not ones that are habitually open.
But I didn’t actually consecrate it as a portal, I was just using it “because it’s there” - similar concept to using an existing chasm in the earth for sacrifices.
It’s more of a “try it and see” approach, than something measurable on a scale - I’ve had good results with it, especially using a pendulum on a flight of stairs, or in the doorway mentioned above. I haven’t done a rigorous double-blind study but both spaces feel different to sitting on our bed or at my desk or whatever, the innate energy in both feels different.
