Hi everyone!

I have a question about the return of stake vs. return of ada.

In adapools “ROA” for my pool has been listed at around 20%, while on pooltool “ROS” has always been listed at 0.0%. Is there a difference in how this is calculated or am I missing something? Or is it completely different concepts and not comparable?

Many thanks,  
Freja

Be patience,pooltool needs more time… for me daedalus still shows potential rewards 0ADA so…  
And yes, I think there is a different formula because for me the ROA is not the same on adapools and pooltool  
Cheers,

Thanks! I’ll just wait for some time then and see if it works later!
