For most people, this is a tool we use daily. What’s the reasoning behind choosing a weekly usage limit instead of a daily one? Is it because the top 5 percent of users tend to have spiky usage on certain days, such as weekends? If that’s the case, has there been any consideration of offering different usage tiers for weekdays and weekends?

I’m just curious how this decision came about. In most cases, I’ve seen either daily or monthly limits, so the weekly model stood out.

It's to make you use it less on Monday for fear of losing it by Friday.
