It is generally a good approach to try and pre-calculate as much as possible in the script, to make the front end expressions simpler and more efficient.

In my attached example I have added two fields in the the data model. The first one is called Delay, and represents the interval corresponding to the difference between expected and registered times. The second field is a flag that is true (-1) if the delay is larger than 10 minutes, and false (0) if the delay is smaller than 10 minutes or if the employee is earlier.

This means that in the front-end expression you only need to address the delay flag to find the data rows that has been flagged.

=count({<IsLaterThan10Min={"-1"}>} Empid)
