I believe you still need 9 stars to unlock the Extra Stage regardless of how many stages you get per credit.

Thanks Zowayix

I Have Other Question:
If you Select Versus Play & the First Round, the 1P obtained AAA & the 2P obtained AA FC for a song, in the Round obtained 6 Stars in Total for the Round?

nope, since a certain update, when you play versus, the star counter is merged, so it's way easier to get ES on Versus.

and the answer to that question is yes.

anyone remembered how much time was needed for someone to clear LITPR on EES back then in X3 era?

Here's a quick time comparison:
- Pluto Relinquish was unlocked as EES for the first time on 2007-12-20. A video of the Expert chart (getting 30 seconds in) was uploaded on 2007-12-21, a day later. It was passed on 2008-1-22, 32 days after that (33 days after the first reveal). Nine days later, it was downgraded to Extra Stage on 2008-1-31.
- Valkyrie dimension was unlocked for the first time on 2010-7-14. A video of the chart (failing at the first arrow after the long freeze) was uploaded on 2010-7-17, three days later. A more substantial video getting up to 385/632 combo was uploaded on 2010-7-25, about a week after that. The full chart did not become known until 2010-10-4, when 513 got up to 623 combo and the last freeze was visible at the bottom of the screen. The VS REPLICANT course was unlocked on 2010-11-02, revealing the song's Difficult chart and allowing it to be played under sort-of Extra Stage conditions after a six-course marathon before it. The Encore Stage itself was not passed until 2011-11-06, four days after the course unlock, a whopping 112 days after the first video or 115 days after the song was first revealed.
- Over The "Period" was unlocked on 2015-3-26 and a video of the first step came out the same day. A video of the second step came out on 2015-3-28, along with FEFEMZ performing the trick to play it on a higher speed mod. It has been so far 8 9 days since the first video and a week since the second, and no one has gotten any further on video. Get settled everyone, this is going to take a while.

I haven't bothered to gather data yet on other Encore songs that took some time to pass such as Tohoku Evolved and Love is the Power -Re:born-, but I highly doubt any of them took even as long as Pluto Relinquish. It would be nice to compile a list of how long it took for each Encore stage to be downgraded though, so we have an idea of how long it will take to see past the first measure of OT"P", since I highly doubt (as with Valkyrie dimension) that it's going to be passed soon in its current state.

According to the old DDR X3 thread:
- 2012-8-2, 6am UTC: LitPR theoretically accessible.
- 2012-8-2, 5pm UTC: First mention of someone AAing TREvo or PRevo and seeing the EES
- 2012-8-2, 11pm UTC: First video. Player gets up to 69/276 combo.
- 2012-8-4, 12am UTC: Second video. Player gets up to 115/276 combo.
- 2012-8-4, 9pm UTC: First pass on video.

All in all it took just about two days.

Part of the reason why it took a little bit might have been because Paranoia Revolution was revealed in Marathon Mode at the same time, and everyone was focused on the new 19.
