Yea, I should totally look at this when I get time. I was a LONG time ago when I wrote it. I am sure things have changed a bit since then. I'll be pretty busy for the next week - so definitely not soon.
I think a lot of the information still applies, and looking at it even now, I think you did a pretty good job.. Maybe you could just take a look at the timing section, as I think that portion needs an update.
Also as an aside:
I'm currently writing a tuner primer for a local club site, and I never really noticed this--till I had to write a how to of my own for others--but the tuning threads with most value are always problem solving threads and never how tos. I've hardly ever learned anything of value from a how to--with regard to tuning--but I have learned quite a bit from reading about other user's issues. When writing my own primer, I found myself trying to integrate most of the information compiled from the problem solving threads, and discarding most of the reductive how tos out there.
Understanding this made it easier for me to compile different issues and explaining them. You probably did the same for your own how to, but I never really thought about it in that way for some reason.
