It would depend upon the project. Pretend your question was: * I'm thinking of writing a book, how many words should I use? The answer is very varied. I read a book to my son at the weekend. 20 words, at the most. The book I'm currently reading is in the region of 1500 pages. Many words. Code is like that. Today I might have written negative 100 lines, and been productive. Tomorrow I might write a template-generation system and have a net positive of a few thousand. It all depends, so much.
