I’m comparing AD&D 2e right now to Delta’s DND house rules and it’s funny how they match up with what Delta insists is more “realistic” or “closer to Chainmail”.  For example, Delta uses the silver standard because he claims that gold coins in the medieval world were never used as such, but as “coins of account” as mathematical shorthand. And then there’s this line from the 2e PHB:

Above these two coins is the much rarer gold piece (gp). This coin is seldom found in common use and mainly exists on paper as the standard money of account.

So Zeb Cook and Delta came to the same conclusion, using the same means...

 

Although, Delta’s stone encumbrance is way better than 2e’s pounds. Anything is better than pounds. Even weight in coins. 

Delta also makes much note of scale, and rules 1 turn to 1 minute, and 1 round to 10 seconds, which essentially makes characters 10x faster than they are in vanilla D&D. AD&D 2e increases the movement speed of characters by the same amount, but does not change the length of turns and rounds. No reason is given, presumably to keep terminology the same, but this could lead the casual observer to assume that there is an incongruity in the system. 

Interestingly, by changing rounds to 10 seconds, 2e initiative segments match up precisely to seconds, elegantly pinning game mechanics with reality.
