That's a blatant cover your ass "warning", they don't honestly expect people to take a break every 15 minutes. That is precisely why such measures work in a legal defence since these guidelines are impossible to follow as they can claim that they exceeded the specification. They probably have the 15-20min justification from the most inconclusive scientific report of the shortest theoretical time that DVT could form. Not practical advice.James Gordon said:Even the system manufacturers say to take a 15-30 min break every few hours........thus giving them a notice of a health disclaimer to prevent lawsuits from happening from events like this.
See courts can't seem to comprehend coincidence when it comes to small likelihood in large populations, Layers say thing like:
"well it would be a million-to-one if it WAS a coincidence, so in all likelihood it was a coincidence. Therefore they must be culpable!"
But a court has jurisdiction that covers MILLIONS of people! There are BILLIONS of people in the entire world, where every one of these coincidences will likely end up in court.
It's like someone going into a lottery company with a winning ticket and them doubting the claimant because:
"come on, there are 25 million combinations of numbers and this guy got every one? It's a fake! Laws of probability say so..."
But millions of people tried millions of different combinations!
Millions of people play video games for years now, this could be entirely a coincidence.
Lets do some simple maths:
55 million Xbox 360s
Average games per 360 = 8
Average playtime per game = 20 hours (some games have 50+ hour multiplayer)
That's 8.8 billion hours.
If there is only a one-in-a-billion chance that any health human at any given hour could have an DVT infarction, we should expect to see about 9 to happen while someone is playing an Xbox 360.
And who wants to bet that every single one gets news coverage?
Why? Because the tabloids and regional news thing that video games are strange, unknown and therefore probably dangerous.
