It's also nice because I can toss it in my pocket and easily adjust pressure (down) when I'm out pre-riding a course, without having to circle back to wherever my floor pump is.
For normal gravel and road riding, I just use my floor pump's gauge, which is far less precise or accurate (+/- 5psi variation on mine).
I'm contemplating doing something similar. My rides are typically multi-surface, and can have a lot of rough singletrack.
it would be nice if I'm riding some extended rough stuff to drop a few psi (and know how much it is) and maybe even pump the tires up a bit later for road use so the tires don't drag too much. That might sound like a bit much, but I feel like it would be good for really long rides, like a 70 mile one I want to do which will have lots of gravel and singletrack.
