Yes I guess you either have live streaming or live scoring and not both. Not sure what I think is better as on many events I have tried to watch live streaming on I get timed out or buffering and then get impatient looking for results as I end up missing who I was following.
I found when I was watching vault and it timed out that I missed the entire vault or saw them presenting to the judges only.
Nothing beats seeing it live, but I guess for many(including myself) it is costly enough to send DD and I cannot afford to come along. Maybe one per year, but that can be tough as well!
