I am so confused about how ratings change nowadays. Look at the two accounts below :
Specialist guy : profile Before doing div2 798, his rating was 1458, he ranked 2027th, his ratings become 1459 (got +1).
Expert guy : profile Before doing div2 798, his rating was 1616, he ranked 2014th, his ratings become 1617 (got +1).
Now I am thinking, how this 2 people got the same rating change? Their ranks are similar but one is 1400+ rated and another is 1600+ rated.
