So what does the score on heavensward indicate?

FINAL FANTASY XIV: Heavensward Benchmark
Score: 4205 High
3840x2160 Maximum DirectX11 Full Screen
Intel(R) Core(TM) i7-5820K CPU @ 3.30GHz
NVIDIA GeForce GTX 980

This is the score I got at 4k max settings but since there is no fps counter have no clue what it means.

There's a table just at the bottom that explains the scores.
