this 40% metric could only be true of they are counting the third-party (with ffmpeg, webkit, etc) but then we cannot say this is chrome.. also there are a lot

this 40% metric could only be true of they are counting the third-party (with ffmpeg, webkit, etc) but then we cannot say this is chrome.. also there are a lot of tools written in python(gyp, grit, ninja etc).. but this dont get into the executable or libraries.. so i would not count (at least in the perspective of this thread) as the chrome itself. since those tools are used in other projects as well and come only with the source code to build things (it would be like to count the gcc compiler as part of the source)
