re: #10 imp_62

Let’s have a pool on what went wrong.
My entries:
1. Failure to adjust for movement in the Earth’s crust in changing the distance traveled in the accelerator. I know that CERN has made these adjustments a part of their analyses, but perhaps recent quakes/eruptions have mucked up their variables.
2. Failure to adjust for recent changes to the Earth’s spin resulting from earthquakes.

Or how about it is just bloody hard to measure a run of over 120 KM through mountains down to a sub cm scale.
