It would be far easier to know rider weight, appropriate spring rate, and sag is set properly than to guess if all the travel is being used.I don’t know where those forks bottom out mechanically. Unlikely to be at the bottom triple. Until you know that, hard to say if too much or too little. I think on street (even on track) you wouldn’t want suspension to reach limits under “normal” conditions. Need room for more extreme scenarios like major dips and super hard braking.
I don’t think accurate internet assessment is possible.
