Suppose you are studying a legacy codebase, one left to you with no documentation. You and your colleagues are by definition the only ones working on it, becuase you call anyone who is working on it a colleague. You are only 1/4th done by LOC, but it's not clear what fraction of the remaining lines are autogenerated getters and setters vs real code. Clearly anyone interested in the codebase should talk to your team.
I should also mention that the 1/4th number is comparable to a "by weight" estimate, but what physicists study is the laws of physics which are not measured in that way. Nobody on Earth knows how much physics there is left to discover or if that is even a well formed question.
