Location updates limit in background service in Android 8

I have a background service with location updates every 12 minutes. We want to test location updates every 5-6 minutes, but in Android documentation we found this:

In an effort to reduce power consumption, Android 8.0 (API level 26) limits how frequently background apps can retrieve the user's current location. Apps can receive location updates only a few times each hour.

https://developer.android.com/about/versions/oreo/background-location-limits.html

Code in the service to receive updates:

    mLocationCallback = new LocationCallback() {
        @Override
        public void onLocationResult(LocationResult locationResult) {
            Location location = locationResult.getLastLocation();
            //...
        }
    };

    mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this);

    mLocationRequest = new LocationRequest();

    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    mLocationRequest.setInterval(TIME_TO_CHECK_LOCATION);
    mLocationRequest.setFastestInterval(TIME_TO_CHECK_LOCATION);
    mLocationRequest.setMaxWaitTime(TIME_TO_CHECK_LOCATION);

    mFusedLocationClient.requestLocationUpdates(mLocationRequest, mLocationCallback, null);

Anyone have tested the limits of location updates in a background service using Android 8?

The limits are a fixed number of times per hour?
