In the first chart does the "rewarded" bit mean the number of contributions that have been rewarded at the time of posting, or does it include contributions that could still be rewarded (are currently in the queue)?

It include contributions that were scored in that week and could be rewarded. I will clarify this in the next report. Please, tell me if you see something wrong.

I would actually say this is a great time to submit suggestions, because there isn't much competition

I totally agree with you.

Thanks for the comment! :)
