Diminishing returns explained

So, you've been told that DR, or diminishing returns, means that you get less when you get more, and that didn't make a whole lot of sense to you.

For those of you who don't run the number crunshing naturally, but still want to really understand what DR is all about.

Picture an airgun. One where we can pump in different amount of air to decide exactly with what speed the bullet leaves the barrel.

Pump in some air. Fire the gun straight up in the air. After a specific number of meters the bullet will turn and start falling back to the earth.

Pump in more air. Enough air to make the bullet leave the barrel at exactly double the speed as your last attempt. Fire it up into the air again.

How far up did it go? Double? No.

Gravity pulls at the bullet. You'll need to fire it at far higher speed than double to reach double height.

Now look at your gear. 1500 dodge rating. Will 3000 dodge rating give you double the dodge percentage? No.

DR pulls at your dodge. You'll need a lot more than double dodge rating to reach double dodge percentage.
