It’s rather a very simple math formula based on the number of steps and parts.

I adjusted the formula by researching online what people reported as the time it took them to build some of the items. ie there’s a linear regression “fudge” factor - but it’s still an extremely simplified “model”, if you can call it that.

The time it takes to assemble Ikea furniture is very dependent on your experience with it, and if you're using an assembly driver or not.

I needed 45 min. Should it be 45 mins then?

Apparently there used to be a built in estimator in the checkout process [1]. I member having seen that somewhere as well, but it's been ages since I ordered online from Ikea, I always go in person to stuff myself full of hotdogs and meatballs LOL
