What temperature do you step up to?
I only do steps for a few styles. Of course I do a Ferullic rest for hefes. But I often do a hochkurz for German styles. For hochkurz, I'm in the mid 140's and step to the mid 150's. I also do a mashout step to 168.
For other styles, I'm usually at a single temp (plus mashout).
62-64(depending on the crop gelatinization temps) 30-60min for attenuation 30 will land you around 1.010-11
72 for conversion and foam 30min
77 foam and denaturing 10 min
If you are not following that schedule, I would argue you are not seeing the benefits from doing a step mash. I would try that schedule next time and see if you notice a difference.
