FAQ
Do negative numbers work?
Yes. The calculator ignores the sign and analyzes the first significant digit of the absolute value.
What if I only have a few numbers?
Small samples fluctuate widely. Consider at least a few dozen entries before drawing conclusions.
Does a low score prove fraud?
No. It simply flags unusual digit patterns. Always follow up with full audits and professional judgement.
