I'm not very sure myself, but here's what I thought.
According to the folding website, the molecule you see is the actual one you're folding, and it updates consistently.
Donator is your ID, which you can change. This is what everyone will see you as on the team list.
Finished WU is how many work units you've finished so far.
p3040_ supervillin-03 is summarised correctly, it's just the name given to the current work unit, they're always random things which don't make much sense (at least not to me
)
Frames completed is just that. For the current example, there are 5000 frames that make up this work unit, and you've completed 1850 of them, when it reaches 5000, that work unit will be complete and your Completed Work unit will increment by 1.
33s/frame is how long it takes to complete a frame
WU end is an estimated time of completion
Hope this helps
(frames are basically a smaller piece of the work unit)
