Answer 1

The simple answer is: it depends.

On your requirements. Which we can't know. You have to understand which of the various approaches meets the businesses goals of your application.

In other words: there can't be a a general answer. If you are measuring clicks on some web page, it might not be a big deal to loose one. But when we are talking about an order from a customer you better make sure to never forget about a single one.
