When the scheduler was first implemented, it would remember the date that it was uploaded. So even though I may have it appear live on Friday, it would remember that it was uploaded last Monday and appear in my subscriber's feeds as last Monday. Needless to say, it was way down in my subscriber's feeds so I never used it.
They did fix the problem at some point because is it working correctly now. I have daily videos scheduled to be uploaded at a regular schedule and they appear correctly in most people's sub feeds. It doesn't always work though because I did a survey from my viewers and it seems that some mobile devices recognized the upload date, not the publish date.
For the most part, it works very well.
