I don't mind at all.
If your question is "How good am I at Free Pascal and Lazarus?" my response would be "good, but not an expert". I am a civil engineer. My interest is in applying Free Pascal / Lazarus to practical problems.
Nevertheless, I have learnt over time the importance of respecting the practices of other disciplines. So, I am more than happy to listen to the experts, and everyone else. I want this book to be as useful as possible to as many persons as possible!
I am quite familiar, however, with the math and algorithm development content of the book.
