browserslist-ga output does not sum to 100%

[stropitek]

I'm not sure if this is a bug but it seems wrong that the output of browserslist-ga does not sum to 100%.

This is then confusing when you run a browserslist query with the using the file with the --stats option

Please find for example the output I had for my website, which sums to ~48.5%

browserslist-stats.zip

To get those results, I enabled the analytics api for my project and created an oauth client id, then configured my terminal with it and ran npx browserslist-ga
