Let’s see if I can answer this. You asked for “exactly”, so it will be a bit more detailed than what you probably expect.
Assume a new recording is made, and there are 3 different people validating at different times.
First two give UP-votes, it passes as OK and the third will not see the recording.
First two give DOWN-votes, it does not pass as OK and the third will not see the recording.
The first one gives UP-vote, the second person gives DOWN-vote (or vice-versa), so it is not decided by these votes, so the third one sees the recording, if he/she does not skip or report it, he/she gives a UP or DOWN vote, so it is the decisive vote.
But life is not so easy… We assumed 3 people validating at different times. But what if hundreds of people are validating at the same time?
See the results here:
And this issue here:
So, there can be ties (e.g. 2 to 2) and it will be continued to be shown during validation. But as I stated in the above post, are 100 up and 100 down-votes OK? 101-100 wins, but there is absolutely a problem with the recording.
Actually, this has been partially solved by the CorporaCreator at the very start, with a decision. See:
# If there are 2+ votes, and down_votes > up_votes, clip is invalid
# If there are 3+ votes, and up_votes == down_votes, opinions
# are diverging too much to be relied upon, and clip is invalid
So, 100-100 votes make it “invalid” (but it is kept being shown to validators - note: It should be moved to other.tsv as it will continue to be processed).
So, yeah, 2-0, 2-1, 1-2, 0-2 give solutions, as depicted in the post you quoted. More opposing votes make it invalid by the CorporaCreator. It is an implementation issue thou…
