I thought variable sampling was more common for this kind of thing.

Stratified sampling could help if there are different groups of accesses, but I feel like discovery sampling is more straightforward for this scenario.

Variable sampling seems more about estimating values rather than finding exceptions, so I don't think that's it.

I remember practicing with judgmental sampling for targeted investigations, but I wonder if that's the best fit here.

I'm a bit unsure about this one. The categorical predictor with 3 levels is throwing me off a bit. I'll need to review my notes on how to handle that in a linear model.
