Flow Control Status - Increase targetRateLimit value

The flowcontrol document (returned db.runCommand({serverStatus: 1}) for one of my mongo deployments is reporting a value of 100 for the targetRateLimit value. On other mongo deployments the value is 1,000,000,000.

How do I set the targetRateLimit ? Is it as simply as updating the document in the database?

Thanks.

Maybe

mongod --setParameter flowControlTargetLagSeconds=20

That change is being put through the approvals process.
