Not to be a spoilsport, but I'm pretty sure all of this is just coincidence. The biggest data sets from multiple players have ended up showing that you get stardust about 75% of the time (from the first three trainer battles and first leader battle per day) and another prize the remaining 25% - which used to always be a Sinnoh stone but as of recently has equal chance of being a Sinnoh or Rare Candy. There's also a small chance (I think like 8%?) to get two rewards instead of one, though they can both be dust.
The only thing that *does* change rewards is the tier you do your daily leader battle on, which makes the stardust reward 300, 400, or 500. Trainer battles are always 500 regardless of League.
