I mean you could use less GCP if the model is more precise aligned using RTK. What we have observed that if GCP count is small or not very accurate(mostly height values) then CC can break the model with visible breakage seam lines because there are too much degree of freedom. If the model is already almost aligned then there won't be such tendency. That is how I understand it helps to reduce GCP. Let's wait for answer from Bentley.
