COGO Traverse Tool Adjustment Residuals
In ArcMap when entering a traverse that doesn't close you could use an adjustment that would return a report of residuals or delta values of how much each bearing and distance changed. This was a key part of the tool. In ArcPro you get an overall closure value (which was also available in ArcMap) but no residual values.
My main use of the traverse adjustment has always been for analysis of survey data outside of the parcel fabric. I routinely use it analyze old metes and bounds descriptions to determine misclosure. And then using the misclosure and the residual values (which have also been removed from Pro) I can find the most likely source of the error. Then I can go back to the record and potentially other data sources to try resolve the error. Often this will include trying this will multiple adjustment types. If you are familiar with adjustments you can external use external knowledge (era of the survey, the surveyor's habits, the equipment used to collect the data, the geography and topography of the land, comments about weather and clarity of the sky during astral observations, etc) to adjust the most likely source of error and get the best adjustment result possible.
The residual values created during the adjustment process are key to this whole process. Without the underlying data to look at and analyze none of the adjustments are really that useful for anything but making a figure close and cartographically look okay.
Also the closure information has also been cut down from what was in ArcMap to what is in ArcPro. It doesn't even show grid closure vs. ground closure anymore.

Hello David,
I have good news for you: when a traverse closes the misclose ratio will instantly appear at the bottom of the traverse pane (1). You can set the misclose tolerance in the traverse options (2) - that will determine when the traverse automatically closes but you also have the option to force it to close by checking the checkbox.
When you use the parcel fabric the misclose information and the calculated areas are written to the parcel and you can use it for quality control.
