Shannon, while I agree with your point, I do want to also suggest that many GA clients do pay for premium service, and in several of my applications I would be OK with stats that are +/- 30% from reality for real-time monitoring purposes.
Basically, answering questions like "is my website down" or "are we spiking volume, like double from normality" would be helpful with a power bi solution. Therefore expediency of data outweigh its accuracy in those cases. Power BI would be ideal because in my situation we have many websites to monitor, so a single google analytics realtime webpage will not be sufficient for monitoring purposes. We would leverage Power BI to pull realtime data from multiple web profiles and once and create rules to bubble up issues or instances out of the norm in real-time.
