Cymoril just shakes her head at all this in-fighting.
"Sara, is there anything i could use to calibrate my magical output? Once i have done that i should be able to train basic skills using Sturmbringer, and - well let's just hope that the others will be up for training as a team by then."

In the movie, Nanoha uses Raising Heart to set up virtual training exercises. They're pretty obviously mostly for training how to use the device and basic skills, since there'd be no need for other training otherwise, but Cymoril needs to get acquainted with her basic skills anyway.
Also a bit of a setup, for both Snowfire (you should know what i am talking about ) and as a contingency if i can't reply in time for other activities.
