It is not changing to show what your DSR's are doing.
Nope it's showing a rolling 30 day total, numbers are updated several times a day but not always immediately after someone leaves feedback. Underneath the graph in tiny print is the date updated.
If you have any kind of volume of feedback it's virtually impossible to tell what a specific buyers leaves. Possibly if they reveal the tenths it will be somewhat possible but even then as old roll off and new rating are added on a daily basis you would still need to know all the exact ratings in between to determine if a buyer gave you say a 3.
