the Art of Zen

I defined a simple measure of top performance and called it the Zen Ratio. It is so named as it came out of conversations with Marc Osgood, the owner of the Zen Spin Works Facebook group, after he had created a top he called the 1:1 that spun in minutes its weight in grams. 17g for 17 minutes. A very beautiful top, and an impressive performance.

We could calculate the ratio of spin time in minutes to top weight in grams for any and every top. The calculation is quite simple: Z = t/m, where Z is Zen ratio, t is time in minutes, and m is mass or weight in grams.
I have done this for all the metal tops in my collection and the graph is shown below.
The highest Zen ratio I have heard about is for a tiny top weighing about 3g that spun for nearly 9 minutes for a Zen ratio of over 3.
As you can see from the graph, the relationship between the Zen ratio and weight is negative, i.e. lighter tops are more likely to have higher Zen ratios.
The obvious challenge is to make a heavy top with a Zen ratio over 1.0. The heaviest top I have with a Zen ratio greater than 1 is a tungsten and titanium top made by John Phillips of JP Momentum. I have heard of a Billetspin Infinity top (weighing about 30g) that spun for over 40 minutes, which is likely the record holder for heaviest top with a Zen ratio over 1.
