The Chinese test used kilowatts rather than watts of power:

All the more possible for small extra forces to slip through the cracks from magnetic fields or whatever.

Maybe so, but it makes it meaningless to compare the measured forces and claim that they've decreased in later tests.

To be clear, the Chinese test used 2500 watts, and this latest test used 700 watts. That is a decrease, but it's within a factor of 4.

On the other hand, the decrease in effect size is closer to a factor of 40,000.
