The performance of SBMT (PPDB + SARI) = 37.91 from simplification/data/systemoutputs/sari30it.test.output.1best?

[Sanqiang]

I tried to use Joshua decoder with the following script:
-cand sari30it.test.output.1best -format plain -ref est.8turkers.tok.turk. -rps 8 -m SARI 4 test.8turkers.tok.norm -v 0
It seems only return SARI = 0.3125145864872819.
I wonder if I configure something wrong?
