Progress in this field broadly means evolution of the seeker's mind through and beyond it's biases and limitations over and over.
The shortcomings you are considering here are in time alleviated by the practice, by using, exploring, exploiting them. That's kind of the challenge.
You might be familiar with the concept that any real illumination is only traslatable in paradoxical words and the problem you expound is why.
We try to go beyond reason but we are stuck within reason as far as available tools. 

The 'side' which makes any result possible is over there in the 'impossible' fields; you (and it) actively work to understand and integrate it. Any effects you'll have will mostly reside on that side. 
It will 'show itself' through the veil of 'real', rather than transform the surroundings of your regular standpoint in an exceptional way: that would give you 0 new insights, whould it?
Otherwordly events as a result of magical practice could very easily trick you into rationalizing those effects having thus changed your material life insted of yourself. 

When your rational mind needs to be convinced to go on exploring (lest it gets again stuck in asking itself why why why all the time), it will get the needful of extraordinary to witness.
You might, for example receive information you could very surely not know anything about previously, and have it from a source distinguishably connected to your practice.
That is enough to confirm you'd be on the right track without risking madness over you house going on an international flight overnight, or waking up floating over your bed.
In fact, if you ever wake up floating over your bed, that will most probably be at a point where you just don't care about that more than having a laugh about it.

My 2 cents, I'm curious to see others' take on this.

After typing I figuered I haven't got an actual answer. Silly me :D

I just focus on not not beeing excessively inquisitive about anything that is not, in and in itself, a result. 
I like to describe metaphysics after having experienced them, so consider my post to be about 'all' (of which I yet don't know). I believe it should stay legit on any step of the path.
In my direct experience the most profound effects hold no name and need no explaination whatsoever. That's why I prefer those and wrote that.

Thinking about it, yes, those 'entities' that do hold names tend to be less wide in scope.
It might be my way of filtering out noise: when something manifests and is not immediately recognisable as 'true', if I'm interested in exploring it I check-ask if it holds any name. 
This is because I rarely ask specific stuff, just wait for what signs each moment shows, reading into what I like and listening to the sounds that ring as true as the truest I know yet.
