I can only speak to my own experience (as if that weren't painfully obvious!), and I'll readily admit I'm no expert, but for my two cents:
I found when initially practicing any Magick or what-have-you that required visualizations, that my ability to visualize seemed weak and unfocused. It was very frustrating. Practicing Resh four-times-a-day over a couple of years has massively
improved the situation, and if there were no other benefit to Resh I would continue practicing it for that reason. My visualizations, though they still stand to benefit from continued practice, have at least reached a point where I am able to sense how visualizations affect the Astral Light. And this has gotten me a sense of the Astral Light itself, which is a thrilling validation that I'm not just fooling myself into make-believe.
So for me, practicing Resh has been a bit like doing regular exercises on the guitar: it keeps the faculty of visualization in shape; but if the visualizations & mental focus are allowed to evolve (like changing up the exercises on guitar, keeping them challenging or at least engaging), progress is continually made a well. (You may not know initially why you need to learn scales on an instrument, but it becomes clearer in time and practice.)
All that being said, posting in this thread is causing me to realize that lately I might be getting a touch complacent with my Resh practice! Time for me to rejuvenate the experience!

I'd love to hear input on your question from someone more experienced as well!
