AFAIK starting scores are outside the boundary condition.
If someone opens an account and immediately goes 30/60/90/120/150/180/180/180... assuming the account doesn't get closed I am pretty sure that isn't a 300 score, and we know 6 months positive history on a single tradeline isn't either.
Single collection on a report, likewise not 300.
I don't really know how to even get a minimum score but I don't think we can say we start there. A no file is a no file, unscoreable which is it's own penalty in this day and age.
