In my teams, we generally set 8 points as something that would take an entire day. Every number after that jumps up in relatively large increments as they are more difficult to accurately determine
Any point with 1-2 is estimated at < 1 day. Some are literally 20 minute fixes, but ... you don't always know that up front, you just generally know it may be pretty small. 2 might sometimes go up to a day.
A 3 is assumed to be a day or two.
A 5 is assumed to be 3-4 days.
An 8 would be 1-2 weeks.
Anything higher is backlogged until it's broken down into smaller segments.
Not sure how well that compares to usages by other teams, but that's one data point for your question.
