The very fact that Google created a special Penguin reinclusion form

It isn't a reinclusion form. It's description is "Feedback on our recent algorithm update ("Penguin")".

the information they are gathering

They are asking for feedback, not offering to take any action.

If I think a page has been wrongly penalised and someone at Google looks at it and agrees, how likely is it that will they manually overrule Penguin for that page?

Has anyone here reported a false positive? If so, what happened?
