CXone v2 Reporting API: Real-time queue stats extraction

Is it possible to extract real-time queue stats from CXone using the v2 Reporting API? The docs here imply near-real-time support, but my Python script returns stale data with a 200 OK. I need the current occupancy, not the 5-minute aggregate. Code below:

response = session.get('/api/v2/reporting/queues/realtime', params={'interval': '1m'})

Why is the data lagging?
