I read this and do not understand it:

The maximum rating change in a match is 50 points; the maximum net rating change in 180 days due to match play is 100 points; and the maximum net rating change in 3 years due to match play is 200 points.

Please explain this, as I am sure my rating has gone up or done more than 100 points in 180 days, certainly over 200 in 3 years. I do not get this.
