Top Performance – by the numbers

As a econometrician/statistician I am always looking at data to see patterns and relationships. With a large collection of metal tops I have lots of data to play with.

After a conversation with Marc Osgood of Zen Spinning Tops who was making a top that weighed 17g that spun over 17 minutes, and which he named the 1:1 top, I conceived of a simple measure that I called the Zen Ratio in recognition of Marc’s achievement. The Zen Ratio  (ZR) is the ratio of the spin time in minutes to the weight of the top in grams. It can be calculated for any, and all, tops, not just long spinners. Marc’s 1:1 top was the first top in my collection to achieve a ZR greater than one.

Of course many other collectors have tops with high ZRs. Below I present data from those collectors of tops with ZRs greater than one. This database will be updated as people send me more reports on their high performance tops.

Most tops have a Zen Ratio less than one. Below is a graph of nearly 400 tops showing their ZRs against the top weight. The inverse relationship (heavier tops have lower ZRs) is quite obvious. Out of interest, the data points in red are tungsten tops.
