How frequent should we input pressure compensation?

We have a pressure sensor in their system, so customer can reflect the value from their pressure sensor into CO2 sensor. Thus, we want to know how frequent should (can) we input the pressure value to CO2 sensor. Is it OK to input the CO2 compensation value every cycle?

For indoor application we have the following assumptions:

a. Device is a placed inside a building

b. The height is not changing every hour

c. The ambient pressure is not changing for every 6 hours

If the assumption is true, then it is sufficient to update the pressure once every 6 hours. However, if someone is living in a multistoried building, then it is recommended to change the pressure when someone move from one floor to another along with the device. This can be identified by recording the pressure sensor value within the system.
