One thing to point out: the Park TM1 isn't known for being particularly accurate in the absolute sense. It works by comparing the tension of the spring in the handle, to the tension of the spring that is the spoke in question. The problem is that the spring in the Park meter, like all springs tends to lose tension when stored compressed for long periods. It's design is such that this weakening will tend to read higher and higher tension values relative to their true numbers. 130kgf from a 5 year old un-calibrated Park meter, might only be 110-120 kgf in actuality.

This is likely why so many folks claim to build to crazy high tensions. They really aren't, but their inaccurate meters are inflating their tension readings.

I recently went through the trouble of calibrating mine, by hanging all of my body weight off of a test spoke. Turns out mine was reading high by ~20kgf. (I've heard reports from others that many read at least 10kgf high, even when pretty new). It's probably good that the design tends to read high, otherwise many more folks would be taco-ing rims and cracking spoke beds at "only" 110kgf on old meters.

This prompted me to build a real test fixture that used a 300kgf crane scale (~$50 from Amazon), and allowed setting tensions all across the range for a given spoke. It showed that my earlier single point calibration (94.8kgf) was good across the whole range of 70-160kgf, at least within the resolution of the Park meter.
