Default Testing Guide

Just out of curiosity is there a guide of some that explains what each test actually does? I thought I had seen something before but don't remember where I saw it.

I particularly enjoyed:

The double-check, which takes just as long as a first-time test, is usually done about 2 years after the first-time test.
I'm finding that most of the double checks I'm doing are 7-9 years after the original.

To a point. I think I was looking at the Prime Wiki and just couldn't find it again.

A more pointed question...what's the difference between a regular PRP test and a first time LL?

LL gives an absolute and provable answer. PRP is gives a probable answer. If a PRP turns up a new MP, then LL will have to be run to prove it.

Unrelated question...

How is rolling avg figured and is it that important? I've noticed my numbers dropping but the computer usage for other things really hasn't changed. It's barely used for anything else.

At least at some point in time this statement was true…

Right - but the page has obviously been edited within the last couple of years, and it's been a long time since DC was about 2 years behind FTC.

I know I was told it can be inaccurate but I'm only at 73%. Changing yhe how often it will be used option changed it I know but not THIS much.
