Hi
@straight-hairdresser-25635, what's currently available is the "Scaled Impact" Difference Type in your results view. This will be "what is the daily total impact as if 100% of users had gotten the treatment?".
You can read more here:
https://docs.growthbook.io/app/experiment-results#difference-types
That will be an absolute value in the natural units of your metric. We don't currently compare this to a baseline (or have plans to do this in the immediate future), but if you have your baseline number in the Metrics view or elsewhere, you can compute the %age yourself.
