Hi my friend
Your observations are very useful.
I started my guide but this thing about fast trainers is a little complicate. One thing to explain, bring other three to question about it. Especially if many people from different levels participate.
So, it turn to something like, finding fast trainers level by level.
Steps calculations thread also is very useful and I recommend it to anyone who is interesting in fast training (also Khris has a very good thread) but the key is to detect the fast trainers before you buy them so to decide if it's worthy if the auction leads to a bidding war.

I 'm little disappointed because new players/forum members seems that not reading this section of the forum and not to searching generally. Every once in a while, someone who read the word nordgen, asking or starting a post instead of put this in search button and examine the results which are very useful and van read many things instead of just an answer of 2-3 lines.
Also if you see the threads of this section, most of them are only questions and many of them irrelative (for example formation questions).

Salute
