Trion amount/ability does increase with training (which Ashihara has said amounts to using your trion) it just tends to stop increasing once you've reached 20, but even after that if you keep training it you can minimise its degeneration (hence why characters like Viza and Shinoda are still so strong even though they've past the 20 years old mark long ago).
