user_Id questions

Occasional Contributor

Hello everybody,

Please help me to find answers on 2 questions i can't find by myself googling:


1) What's user_Id lifetime? when it dies - after 6 months of inactivity or just after 6 months?

2) How sample rate works exactly - on user_Id level or hit level?
