In order for training to be effective, it has elicit an effect. That might seem obvious but many people miss it. Yes, a novice can "project" all day, every day and eek out minor improvements. The foot-cutting thrutching they call climbing elicits a training effect for them.
At some point a finer distinction is needed. They are many ways to elicit a training effect. You can fonder the fingerboard, switch to thrutching up a campusboard, or even try to structure your climbing to match your goals. Since they are novel stimuli, they will elicit a training effect. Some methods will have more direct and longer lasting effect on your climbing, but they will all work in the short-term.
If you aren't seeing improvements (i.e., outputs are the same), you need to change your routine (i.e., change the inputs). Any change is better than doing the same thing that is not working.
