Streaming data in dashboards, reports using Microsoft Power BI REST API - is 10K rows/hour enough?

I need to understand if in my scenario 10K rows/hour for streaming data would be enough.

1) There would be aprox 10 users of the dashboard, but am I right, that user count should not matter, because they would all use the same Dashboard? 

2) What does this 10K rows/ hour mean? Does this mean my application can send changes for up to 10 000 rows that reside in my power bi service per hour? 

3) What if my app has to send updates for 12 000 rows - does it modifies on power bi service side 10 000 rows and what happens to those 2 000 remaining rows? Are the changes discarded (how can my app know that some changes are not sent to power bi service?) or is only refresh for the remaining rows postponed to the next hour?

4) What happens if I have a report with 20 000 rows and let's say 10 rows are changed - then when my application pushes data to power bi service, in regard to this limitation - this means changes to 10 rows, not the 20 000 rows?

And also can this update through Power BI REST API co-exist with daily refresh, that is provided for free edition clients?

5) I see that there is also a Dashboard Tile refresh - I guess that means refreshing tiles from the data that are already in the Power bi service and this should not "eat" that 10K rows/hour "bandwidth"?

Thanks in advance!
