I would not do –0.3. It would be up to the value of the connection.
The D-panel would reward EVERY attempted connection. I’d say 1 second is a good threshold. And I agree with about ignoring arm movements. The E-panel would deal with that. They can deduct up to the connection value earned, so either 0.1 or 0.2.
If there is doubt, the D-panel should say something — they can talk to the E-panel. In fact, on vault, they even hold up the script for the vault they are crediting when the E-panel might have doubts. ETA: they don’t need computers for this. They can talk or show their scripts.
ETA: I see Aeris basically agreed with what I am saying. I wrote this before reading that response… Cool though.
