  1. well that although is not a proof. I spent 12 years on a quite large project (1.4 MIllion code lines of C++ when I left). The measured time fixing bugs was roughly 4% of the team development time. We did not use TDD.. so one cannot assume that not using TDD generates buggy code. Quality of code comes from quality of the team, nor a process. TDD is a way to solve the issue of how to force a minimum standard on teams on another angle of approach.

  2. The 10 lines of code although must be taken with a pinch of salt (i.e it is not for 100% of cases). For example if you are writing a code that has a directly mapped meaning, split it can cause confusion. One example is math code. If you take a invert matrix code and start to fragment it you are splitting a well defined and known concept and that very likely will cause MORE confusion (because you start to create arbitrary cut point that do not exist in the concept)
