limit period less than 1 second

Hello everyone, I use automation to link my two devices that are both on the system.
When one qualifier depends on the other and needs to be as updated and accurate as possible, that’s why I use automation. The problem is that you can’t choose a limit limit period less than 1 second. I checked and once the option was possible. Anyone have any ideas?

Can you explain more about your need to update a datastream more frequently than once per second?

Pete.
