Hi Matt, yes of course. You want to know how slot time and duration are working together. So first of all services need to have duration all of them. Example 1 if you set duration 60 minutes and slot step 60 minutes and have connection that is from 08-12h then you would have slots like this :

slot 1: 08-09
slot 2: 09-10
slot 3: 10-11
slot 4: 11-12

so customer can book only on full hour. Example 2 if you have same duration 60 minutes and slot step 20 minutes and connection that is from 08-12h in that case it will look like this.

slot 1: 08:00-09:00
slot 2: 08:20-09:20
slot 3: 08:40-09:40
slot 4: 09:00-10:00
slot 5: 09:20-10:20
slot 6: 09:40-10:40
slot 7: 10:00-11:00
slot 8: 10:20-11:20
slot 9: 10:40-11:40
slot10: 11:00-12:00

so your customer can book on each 20 minutes interval. But if someone book for example from 08:40-09:40 it will make a gap that can't be filled (08:00-08:40) because it is less then service duration. Best regards, Nikola
