It can all fit in 1/2 snap.
Check ai mod.
A lot of those spacing errors are ai glitches, but some may check out as infractions.
00:27:727 (4) - The beat for this is on the previous red tick. I think you can get away with placing it on the red tick and stacking it with 3. Then you'll just have to reapply distance snap to the notes after it. The fix might have to include altering the angle that the slider ends at or a snap sacrifice can be made. It's a suggestion. You don't have to do it, but I noticed it right off without even looking at the notes in the editor that there was no sound behind note 4.
00:32:727 (1,2,3) - This doesn't have to be changed since you added the whistles that mask the sound placement. It could be done though.
http://osu.ppy.sh/ss/1243400:36:669 (1) - Start this on the red tick at 00:36:765 -
00:45:035 (1,2,3,4) - Why did you change the whistle pattern? Shouldn't it be the same as the previous combo like this or vice versa. Just a suggestion.
01:08:881 (2) - Center this. Turn distance snap and grid snap off and place it in the middle of Note 1 and 3.
01:32:727 (2,3,4,5,1,2,3,4,1,2,1,2) - Move right 1 unit. (Distance snap error)
01:36:958 (3) - Move up 1 unit. (Same)
Hard 02:37:727 (2) - Reapply the distance snap to this. It will move the note up and left 1 unit.
03:00:227 (1,2,3) - Eh. I don't know about this. It seems awkward to play.
03:30:804 (1,2) - Align these better?
03:57:054 (1) - Belongs on the previous white tick. 03:56:958 -
Make sure you adjust the inherited section after replacing the note.
Lunatic00:15:804 (2) - Move up 1 unit (Turn off distance snap for this) (Fixes snap glitch)
00:16:765 (3) - Move up and left 1 unit. (Distance snap = off) (^)
00:38:496 (2) - Move right 1 unit (Distance snap = off) (^)
01:05:035 (2,3) - Move down 1 unit. (^) (^)
01:30:035 (4,5,6) - Slight unequal spacing.
02:14:650 (3) - Move left 1 unit. (Snap off)
02:40:612 (4) - Center this. Turn off distance snap and grid snap and lower it a bit.
02:53:112 (4,5) - Unequal spacing. Expand.
Fix for this
02:53:304 (5,6) - Move this down and right two, then move note 6 down 1 more unit. (Turn off distance snap for this, because all the notes in this combo are spaced slightly less than the distance snap.)
03:01:381 (4) - Expected this to be a whistle.
03:36:573 (9,10,11,1,2,3,4,1,2,3,4,5,6,7,1,2,3,4,5,6,7,8,9) - These I believe can be centered by moving them all to the center vertical line. (a couple units right) This will also fix the spacing issue between 03:36:381 (8,9) - these notes. They are spaced too great from each other are the reason why the combos after them are not centered right.
03:43:881 (2,3,4,5) - Unequal spacing.
03:46:958 (4,5,6) - Another slight spacing discrepancy.
03:48:688 (6) - Move down 2 units. (Fixes spacing)
03:52:342 (1,2,3) - Slight unequal spacing. Either apply distance snap to 2 and 3 or shut it off and equalize the spacing manually for a tighter fit. I found that applying the distance snap made it line up surprisingly well to Note 4 in the combo.
http://osu.ppy.sh/ss/1245003:55:804 (2,3,4) - Any particular reason why this has weird spacing?
It's good enough for a star.
