At least some of them, yes.

- NOTE: When opening the report in excel or google drive, there may be answers that appear to be the same on separate lines with separate counts. This is due to the fact that the answers were actually answered differently by the student. For example, they may have entered "0000" instead of "0".  Excel will display those two inputs as "0".  You can confirm this by viewing the raw data in a text editor.

- If problem content was changed after release, the answer distribution will include the totals for the whole problem history.  You will not be able to tell which answers were given to which version of the question.  (e.g. if you change "What is 2+2?" to "What is 2+3?", you will likely have a distribution consisting mostly of 4s and 5s, but you won't know for sure which answers were given to which question.)

I can't think of a good way to describe the date issues in the general platform docs.
