I'm a scientist (Astrophysics to be precise) and I love looking at stuff like this, especially for the red-flags and supposed "trends" that aren't there. For example, take a look at this page:



Those three graphs show a supposed "trend", with the blue lines are the errors in the measurement. Not only do they deceive by scaling the graphs from not-zero to show the maximum apparent difference, but if you believe their error analysis is correct, the fact is that all three of those graphs show no measurable differences between any of the frame materials in any of the tests.
