It's indeed a theory that many of us have also been thinking about. After a number of chests drops you don't get chests drops anymore or just chest drops with bad loot.

Baseplates are a lucky thing. If you're starting the game, you really need them, if you are having around 20 minifigures built, you don't need them. There's not really a good way to get baseplates, the only there is, is the lucky way.
