I keep a list of what I finish, when I submit it, and when it passes. I need to start listing the date it gets added to the panel, but here it is: http://www.bstrader.net/?p=198
So I have only 1 song on the panel right now, 12 songs waiting in the inbox.
The song on the panel now was subbed on July 13th, 2013 and added to the panel on March 13, 2014 which is a difference of 8 months. The song is still being judged. You can cross-reference some of those dates for songs that are posted, for example;
November 21st, 2012 – Death Lives (submitted)
March 17th, 2014 - Death Lives (posted to OCR)
From and including: Wednesday, November 21, 2012
To, but not including Monday, March 17, 2014
Result: 481 days
It is 481 days from the start date to the end date, but not including the end date
Or 1 year, 3 months, 24 days excluding the end date

A huge difference being if you make something they like as much as Bubble Dragon, they'll go out of their way to have it posted within a couple days.
