Alright, I started on April 1st. Traded in an EV'd Level 30 team (Kingdra, Ampharos, Marowak, and Xatu) from Platinum when I reached Jasmine since I didn't really like the team I was using at the time. I've beaten all of Johto's Gym Leaders and caught Lugia with a few Ultra Balls.
I traded some other Pokémon over, too. Planning to trade more Pokémon over from Platinum once I catch more Pokémon in SS. Or I might breed some of my traded Pokémon instead, since I need/will need the 'Dex entries anyway (hopefully I have a Ditto stored somewhere on Plat...)
I've just gotten past Tohjo Falls, and my Darkrai found my first Shiny Leaf.
