What's the accuracy of RoomPlan scanned objects?

Let's say a 10-feet wall. Would RoomPlan return 11, 10.1, or 10.01 feet? Thanks a lot.

I seems to often work to 15cm, it has a claimed accuracy of 90%.

How we know the real measurement from the object who have captured by roomplan , example oh i know that the wall is 2 meter

What's the accuracy of RoomPlan scanned objects?
