the static performance is better than nonstatic performance

[echo-cheng]

I want to ask if all datasets use the same hyperparameters?
I didn't modify the hyperparameters and train model on the TREC, but the score I got is showing like:
static:
dev scores: 0.922, test score:0.936
while nonstatic:
dev scores: 0.938, test score:0.928

Or could you explain the score in scores table?，It's dev score?
