Has anyone else found Alura’s revenue estimates way off?

I’ve used Alura for about a year, mainly for sales and revenue estimates.

I checked my own Etsy shop today. My actual lifetime revenue is around $1.6k, but Alura is estimating about $10.6k.

For comparison, I also ran the same shop through Slyst, a tool I’ve been working on, and it estimated about $1.34k.

I know none of these tools can be exact, but that gap with Alura surprised me. It makes me wonder how much weight we should really put on revenue estimates when researching other shops.

Has anyone compared Alura or EverBee against their own actual shop numbers? How close were they?
