What can I do to get a better meassuring?

Start here: What Is the Respiration Rate Feature on My Garmin Device?
What you should check is the HRV measurement. The actual respiration rate is not measured so counting your breaths and see if the watch shows the same will not work. To get better accuracy you should use a HRM chest strap, but it will still not show the exact same breaths per minute if you intentionally breathe in a certain way. The average value or the change over time is more interesting to look at than the current value.
