What do you mean by e3 and e6 and decades?
Check out this post I made a while back - I stumbled on a blog post explaining the weird patterns to all the values of the common parts. There's a reason for those oddball values, turns out!
I got curious again, because the E3, E6, E12 thing didn't stick the first time I found this out,
this blog post summarizes it well. Most of the values used in the builds will have these components in them (4.7, 47, 470, etc.)
E3 decades - 1.0, 1.5, 2.2, 3.3, 4.7, 6.8
E6 decades - 1.0, 1.2, 1.5, 1.8, 2.2, 2.7, 3.3, 3.9, 4.7, 5.6, 6.8, 8.2
