First you need to think about (and document) what your numbers mean and 
how they should be organized for analysis.

Why is this so smaller than the next numbers.  Are all those digits 
significant, or are they mostly just noise -- and best dropped by 
rounding the number to a few significant digits.

After exactly 3 numbers in this range?

Answer the questions above before writing code.  .csf is likely not the 
best format to use.
