There’s a reason people refer to it as “ramping up”, as you become familiar with the environment and code base you become more and more productive until more or less plateauing a while later. It’s not really useful to categorise it as binary productive or not productive.

So you are telling me you never qualified at a workplace with longer than a month probation period?

Do you see how that putting-words-in-others-mouths looks? It's rude and does not contribute too any kind of productive discussion.
