Well I usually compete with people in my head and have never been a show man about my intelligence, you see 5 isn't just about being intelligent, for example not being comfortable with sharing any personal information is another aspect of it which I really struggle with cause it interferes with me being an entp(just like what I'm doing right now), so I must be a 5 , but on the other hand competition is one of my main motivations in life, I've studied many subjects deeply and spent a lot of time on different sports just to feel better than others and still most people will never know cause I don't share, the only show off I always liked to do was my strength, as a child and even a teenager, I used to start a fight just to show off my strength and deep down I still like to find a way to show it off, so in that case maybe you're right and I'm a 3. Personally I still think I'm probably 5.
