In theory yes, but as usual in practice it’s not so simple!
The main difficulty we face with suspension set-up is the amount of variables at play. Different frames, forks, shocks and component combinations, rider weight, balance, style, experience, strength, terrain, ground conditions, weather, altitude, temperature… The list goes on. All these affect how an ‘ideal’ set-up will be executed. You could have two riders, exactly the same weight, build and bike, however both set-ups could be different depending on the riding style. If one rider is more aggressive or rides with more weight on the front then the set-up will have to provide more support than a set-up for the other person who maybe doesn’t ride as aggressively or rides with their weight more rearward.
Many people use ‘factory recommended settings’, which are generally a good staring point to tune from. But that’s all they are, a starting point! These are worked out for the average rider, however taking into consideration some of the variables listed above how do you decide who the average rider is? ‘Average’ in this case is very subjective! Using this method is time consuming and often confusing. For example too much low speed compression can give the same feel as too much high speed rebound, so if the feedback feels similar how do we decide witch one to adjust? This is where data comes in!
