You can't really say one piece of evidence is better than another piece of evidence unless you can quantify it in a meaningful way. Agile points are an example

You can't really say one piece of evidence is better than another piece of evidence unless you can quantify it in a meaningful way. Agile points are an example of something quantified in a way that isn't meaningful, while performance timing on an algorithm can be meaningful. Many things in programming languages like a for loop vs. recursion cannot be quantified meaningfully.
