James, thanks for the extra info. I've done a bit of digging
and it looks like Breeze (Connect) records the LAST action taken by
a visitor, so if for example, a visitor passes a particular
training, and then re-opens the training for a partial/incomplete
view, the training report will register an incomplete, while the
visitors' report will show a completion/pass.
There may also be a setting in the Quiz Settings while in
PowerPoint that may alter this behavior, but this will take some
experimenting. I'll try to post any new findings here, but still
open to others' suggestions.
