Pi formulas exist in nature. Then there are formulas by Ramanujan, Chudnovsky and possibly others which are faster.
The Wikipedia formula of k!/(2k+1)!! is fast. This is nature. This is what I claim as Measuring Behaviour equation. It exists in nature.
Then there is another formula(2^n)/(comb(2n,n)). This too is nature. This was discovered by #PythaShastri. This is also Measuring Behaviour equation. It exists in nature.
The expression k!/(2k+1)!! gives pi to 6 places in 25 steps in Microsoft Excel.
The expression (2^n)/(comb(2n,n)) gives pi by 2 to 7 places in 25 steps in Microsoft Excel.
The second expression may be a little faster. Of course, Ramanujan expressions or Chudnovsky expressions are very fast. But this expression of (2^n)/(comb(2n,n)) will possibly come in top ten fast expressions of the world, if not the top five.
Also the two expressions are of nature.
