OK. I've been away, and when I came back we had "Usergate" and the four retrospective scores.
The panel (i.e. me) has considered all submissions, and has come to the following conclusion; the scores will be admitted.
The reasoning for this is as thus:
(1) others have submitted retrospective scores which I have included
(2) I cannot be bothered to track back and remove them, because I'm lazy
(3) only two responses were received to the "does the team think"? post I made; 1 in favour, 1 against
(4) the "in favour" post said "it's only a bit of fun". Which it is.
(5) no one in the top 10 complained.
However, as of now, the panel (i.e. me) is instilling a new dictum; any scores for a quiz received after posting of the subsequent quiz will no longer count. So, you have about 16 hours or so left to get a score in for this one.
With all that in mind, the "just for fun" league now looks like this...
