I just got Pokemon X. I chose Froakie and ended up with a modest nature (which is perfect). He's Sp.ATK and Speed based, so I've maxed out both on the super-training. His 'limit' has been reached, and he is still level 5 (not even battled yet).

Do I keep his super training graph the same through his entire life to eke out the bonuses? Have I done it right?
