Let's test:

A1 = 0
A2 = 1500
A3 = 1400
gives A4 = -11,51792001

I round it to nearest integer = -12, right?
yep. the rule of thumb is about 4 points per 100pts difference, starting from 16pts with even ratings.

win a 100pts stronger opponent, you gain 16+4 = 20
win a 200 stronger, gain 16+8 = 24
lose to a 100 weaker, you lose 16+4 = 20
lose to a 200 weaker, lose 16+8 = 24

it's quite linear if the ratings are within a couple of hundreds of point. 25 points difference for 1 point gain/loss.

There's a nice greasemonkey script for firefox that will calculate the ratings change for you in the game screen, I think you can get it over in this thread.
