Here are Temari's intelligence feats:
Her fight against Shikamaru displays her superiority in analytical/deduction skills and she has the knowledge advantage in this fight. First off, right after seeing the shadow possession, she deducted that Shikamaru can't change the surface area his shadow covers and that he can use shadows created by other objects to extend his own shadows but that he can't manipulate those external shadows (

. The fight at this point only lasted a few minutes so her being able to notice such slight differences is a superior analytical feat compared to even Neji, who has the advantage of 360 degree vision. Also Temari's mathematical skills surpass even those of prodigious astronomers, mathematicians, physicists and engineers. She managed to accurately measure the distance between her and Shikamaru, to the nearest centimetre, without actually measuring it (

). Later on, she somehow managed to measure the angle the sun had travelled through the sky and managed to measure how long Shikamaru's shadow can extend using the knowledge of the limits of Shikamaru's shadows previously and the change in position of the Sun (

). It is quite perplexing for her to be able to do all these calculations inside her head in the heat of battle without having to use a calculator or paper to do so. In other words, she is both a human ruler and calculator. As a matter of fact, I don't recall anyone in this manga, or in real life, having such great mathematical skills. Although, I might be wrong about this so show me an example that exceeds this.
