It's pretty much impossible to "capture the context, nature, and substance" in a summary ... particularly substance. There's a lot of stuff not included in an abstract or a summary that you have to find in the report. A drug trial may say the drug under consideration wasn't effective for use, but the body of the report may still show that it was somewhat beneficial in some people under limited conditions. I've watched many times people read a report, leave a meeting, or witness and event and have different versions without any intent to filter, deceive, or misinterpret things. It happens.
