Reading low speed mods

[Breakdown16]

Hello FFR. I've been very inactive lately, and I'm considering getting back into FFR and Stepmania. There's one question that I have that might influence my decision.

Way back when I started playing, I used upscroll. Like the majority of players, I steadily increased my speed mod to spread out the arrows, ending at x2.0. (After quitting for a while, I now hover around x1.5, though I hardly play.) However, in doing so, I lost my ability to read low speed mods. FFR's kind of interesting in that it's one of the few rhythm games that's always constant in scroll speed - other games tend to have varying speed with varying BPMs.

When I started playing IIDX and BMS (downscroll games), I was able to read on a greater variety of speeds due to being forced to deal with BPM-changing songs. I want to be able to read low speeds on upscroll too, but the thought of having to spend weeks/months relearning how to read slow upscroll speeds is kind of discouraging.

Overall, is it "practical" or worth it to learn to read at lower speed mods in order to enjoy X-mod files on Stepmania or to fully appreciate the BPM changes in a file? How many of you play on X-mod? How long did it take you to learn to read slower speed mods?
