Frequently Asked Questions
What happens when items cannot be divided evenly?
If you have 10 items and 3 groups, you can choose to distribute the 1 leftover item to Group 1, or keep it in a separate Remainder Group.
Is the distribution random each time?
Yes, every partition performs a fresh Fisher-Yates shuffle using hardware cryptographic randomness.
What happens when the item count is not divisible by the group count?
You can choose between distributing remaining items evenly across the first groups or keeping leftover unassigned items in an isolated remainder roster.
