Nonstop course scoring?

Okay, I have a kind of embarrassing guilty pleasure: easy nonstop courses. One of my favorites is Eurobeat (difficult). It's fun, and I love the songs. So I've played it a couple of times.

Now I thought maybe I was just getting too many greats, but my best on the course is 25 greats (full combo). The full combo for the course is over 800. No NGs, no nothing. I don't know how many perfects I got, but I didn't get a ton of them either. The score I got was 925xxx.

So why won't it give me the AA for this course? What am I doing wrong? Am I doing anything wrong? Will it just not let me AA courses that have no heavy-level songs in them?

I'm confused and slightly frustrated. Can anyone help?

If it's SN-X then you need at less 950xxx to get an AA. My advice is get more Marvelous steps.

---

I know that, silly. But from my understanding of SN/2 scoring, based on the number of greats I got, I should've gotten a high enough score for a AA. That's why I'm confused.

---

I think Marvelous count's a 10 points more as a Perfect, but getting a lot of them will start adding up. If it's an easy course, then that means less steps, that means each step is worth more and there's less room for error.

Okay, but the max combo is somewhere over 800. Let's say for sake of argument it's 800.

At 800 being the FC, each perfect is 1240 (b/c each marvelous is 1250).

Keeping my 25 greats, if the rest were perfects, my score for perfects would be ~775 x 1240 = 961000. That alone would give me the AA! D:

It just doesn't add up. This is why I'm confused. D:

Another way of looking at it: 25 greats for four songs means approximately 6 greats per song. Do you realize how few steps there would have to be for that to bar me from getting a AA?

So this is my question. How exactly does the scoring system for nonstop courses work? It's not like regular scoring, or else my 25 greats FC would have gotten me a AA.

Translated roughly:

Each stages' dance points:

STAGE 1,2: (total notes + freeze arrow) x3
STAGE 3,4: (total notes + freeze arrow) x4
STAGE 5,6: (total notes + freeze arrow) x5

Score:

(Points per dance point)x(Number of MARVELOUS+O.K.) x3 (x4 for stage 3,4; x5 for stage 5,6 and so on...)
+ (Points per dance point)x(Number of PERFECT) x2 (x3 for stage 3,4; x4 for stage 5,6 and so on...)
+ (Points per dance point)x(Number of GREAT) x1 (x2 for stage 3,4; x3 for stage 5,6 and so on...)

Wait a second... for the second and third lines under the "Score" part, do you mean to have Perfect and Great in place of the Marvelous?

Wait, even with that, I don't really understand how this works. Gah, why did I have to be the stupid one. >_>

Oh oops, rofl, damn my copy and paste.

Okay, on SN2 a Marvelous or OK is worth:
3 DP on stages 1 and 2
4 DP on stages 3 and 4
5 DP on stages 5 and 6
...and so on if there's more than 6 stages.

Perfect is worth 1 DP less than Marvelous.
Great is worth 2 DP less than Marvelous.
NG is worth nothing at all.

The game adds up all the total possible DP across all songs before you even start (call this MaxDP), and keeps a running total of how much DP you've earned (call this CurrentDP).

Every time you hit a step, the game adds the DP earned to the running total, then plugs the new running total into this formula:

1,000,000 * CurrentDP /MaxDP

And that, rounded down to the nearest point, is your score after that step.

A score of 950,000 (95% DP) is a AA.

Or in short, the later songs in a non-stop course are weighted to a higher value than those earlier on. So you are probably getting exceptional scores on the earlier songs, but a few too many greats on the last one which brings your sum total down.

Actually, the difference between a Marvelous and a Great is the exact same (2 DP) on every song. The only difference is, on later stages in SN2, you get bonus points just for hitting the step.

Here's a different way of looking at it:

Timing score for each step:
Marvelous: 3 DP
Perfect: 2 DP
Great: 1 DP

Survival bonus (SN2 only):
0 DP on stages 1 and 2
1 DP per step hit on stages 3 and 4
2 DP per step hit on stages 5 and 6
3 DP per step hit on stages 7 and 8
(And so on...)

95% or higher is a AA. 100% DP (i.e. all Marvelous; all Perfect won't cut it) is a AAA.

To make a long story short, the reason he didn't get a AAA is because everything is rescaled so that a Marvelous is the norm instead of a Perfect. Especially since Extreme and SN don't give points just for hitting steps on later stages.

Here's another way of looking at it, for SN:

A Marvelous in Nonstop is worth the same as a Perfect in normal play.
Perfects and Greats are worth 2/3rds as much in Nonstop compared to normal play.
So, even if you get very few Greats, your Perfects are still bringing your score down.

Frankly, a score of 92+% in Nonstop or Challenge is a really good score in my book.
