Should You Close a Bunch of Old Upwork Contracts at Once?

What will happen to your JSS score if you closed a bunch of inactive Upwork contracts at once? I've let too many contracts stay open even though the project has been long done so I'm experimenting with what will happen if I clean house and close them all now.

As per the other comment. He is correct. I’ve gone off upwork 8-12months and didn’t close out 6-7 jobs. Before this my JSS was like 64% (assume open long term jobs no money earn). After close updated to 100%.

As per my research, closing contracts and not getting any feedback does not effect your JSS. JSS is only effected when a client leaves feedback (positive or negative).
