Really? One team estimates in gummi bears and delivered forty gummi
bears worth of stories; obviously, Team Gummi Bear has a velocity of 40.
The other team estimates in pomodori and delivered twenty pomodori worth
of stories; equally obviously, Team Pomodori has a velocity of 20.

Now, based on that information, can you tell which team delivered ten
running, tested features and which team delivered twenty?

Well, it sounds like it would take a pretty narrow set of ideas on
how to improve velocity. In a discussion on that, I would hope that
ideas like learning, better tools, higher morale, and better
communication would come up.
