Newbie question, is there any benefit from getting the knee down?

I did my first track day last weekend (posted a pic earlier) and I was able to get my knee down in my second session, however, after I stopped trying to get it down and focused on other mechanics I was much quicker and felt way more comfortable in turns. I guess I was probably doing it wrong or something but is it just a bragging thing or does it improve anything/necessary to become fast? via /r/Trackdays https://www.reddit.com/r/Trackdays/comments/e6qo2y/newbie_question_is_there_any_benefit_from_getting/?utm_source=ifttt
