The fact that his counterpart shifts corridors almost as soon as he starts trailing him is a good indication that Conan isn't there yet. He sighs, coming to a halt. Shinichi's almost entirely noiseless, the years of training allow him to move gracefully and stealthily, while his control over his body allows him to reduce even his breathing. The monk that taught the Kudous was able even to slow his heartbeat; Conan ... is he going to have to start all over again?

The memory of his Dad's survival training makes him wince, and he resolves to try again. He concentrates on becoming aware of, taking control of, then carefully reducing his breathing before picking up the trail again.
