Yes, I've seen farrier trims where nothing was going to help with one trim, but getting closer to what should be.
I've also seen horrendous feet come out looking pretty good.
I usually go 4-8 weeks depending on the growth and especially the change in angle over the period. Hooves tend to run forward, and I try to catch it where it can be made correct again in one trim.
I find that with average feet that just need a maintenance trim, the farrier trims back to where he needs to and really doesn't gauge or watch the horse move unless there's a problem, like interfering. Or some other problem. He would need to measure and see the horse move and see what he can get away with to correct the horse without causing detriment to the horse short or long term.
