Why is my Vercel Analytics score so low?

I'm getting 90+ on performance on Lighthouse tests and Google PageSpeed Insights. However, on Vercel it shows 45 performance score with LCP and FCP of > 10 seconds. Anyone have an idea what the problem could be?

vercel analytics is useless they've bought some people who are good at analytics so it might get better soon but for the time being its useless

sorry ive never really researched this in depth tbh just seen clearly incorrect scores over and over ive seen projects that get a vercel analytics score for each staging deployment and it will change enormously between two commits even though there were no actual changes to the website

@KamilT I see. Something interesting is if the site gets used the score goes up, while there's not many users the score goes down
