(Bulding difficulty rating system)
The BDRS is a system I developped for my blog that helps to to know how easy or hard the model is to build. Though, don't think Peach's Castle is 7 times harder than Yoshi's house diorama; this is a subjective rank. It only means it needs about as much knowledge, experience and capability as the Diddy Kong model, and more than lower rated models. There is no precise calculation! So, a model's rating may change with time.
NB It will never happen a model on this blog get with a 0 or 10 BDR.
-SMW's Yoshi's house diorama
-Kalimari desert's train
-Shine Sprite v.2.0
There is not any models with an higher level than 8/10 yet.
