I noticed this: "broken it down by language using source lines of code." with SLOC it needs to be normalized between languages for example assign the factor 1.0 to C and have other factors based from this one. "Effective lines of code represent a metric independent of code and language style." I couldn't find any factor comparison tables on the WWW.
