Guild Wars 2

so it’s the rating not the points that effect whether a server comes 1st, 2nd 3rd, etc.?
Is there any sites or information to help me understand how a server increases/decreases its rating?

Your warscore determines if you server wins the match-ups. All bases (camps/towers/keeps) your server owns equals your PPT (Points per tick), which is added to your warscore every 15m. Points not from tick are what your roamers/havoc squads mostly get. Its the points that are instantly added to your warscore. Example stomping people with bloodlust gives 1 instant point, yaks (traveling on the road) give 3 points, sentries give 1 point when it flips. Since bloodlust effects all borderlands capping it gives a huge advantage to your roamers. It can add as much as 150 instant point every 15m from stomps.

Rating determines the tier your server is in, but rating take awhile to adjust. When any WvW guild transfers that effects a servers rating. Since you will lose some coverage. Your coverage is just the times which you server has a guild or zerg roaming the maps.
