Why only a 3/10?

Just an accumulation of little things, like starting off with using a screwdriver the wrong size for the screw heads, not taking the trouble to sand smooth the surfaces where bits had been cut off, laying on thick coats of spray paint on top of previous coats that were still wet, and so on. A bit more attention to detail would have produced a much better finish.  A bit harsh for some maybe, but I'd judge myself the same way.
