I think your explanation of how the Grand Exchange prioritizes old vs. new items is only partially correct. I do believe that this is how the system generally works, especially in the case of items with low buying limits and low volume i.e. rares.
However, I believe this is only partially true in the case of high volume items such as logs, runes, etc. Following your theory if someone placed 10 million water runes for sale at 7 gp each, all of their runes would have to sell before anyone else would be able to sell water runes at 7 gp. The only way new sellers would be able to sell their water runes is if they place an offer below 7 gp.
A simple test with two accounts both selling 25k water runes for the same price will show this theory to be flawed. It is true that the account that placed the offer first will begin to sell it's runes first. However, the second account to place an offer will begin to sell it's runes shortly there after and before the first account has completely sold it's 25k runes.
If the G.E. didn't work this way a single seller that had a massive quantity could create a price ceiling that no one else on the market could sell above. This would result in a more volatile system that could be more easily manipulated. I do believe that the Grand Exchange gives slight favor to older offers, however, it is still a mystery how it fully works in prioritizing large offers.

Interesting -- thanks for your post!
I wonder if the old vs new prioritization works like this:
Old offers get prioritized over new ones ONLY for the first player that buys from the old offer, then they all get thrown into the same pool from which items are drawn randomly?
Dunno :o, I really hesitate to claim the GE is random though. I believe my example with Rune 2h swords is correct but I will add a note to that section explaining what you said.
Are there any other parts of the guide that you dispute?

Most of this crap aren't "secrets" at all... it's common sense. Ok seriously who didn't know that's how items were bought and sold if you're older than 13.
Title is very misleading. Should say something like "grand exchange basics". Took me first time using the grand exchange to figure out how buying and selling items between players worked...
