02:11:908 same. never use 1/4 slider in normal diff
but want to say something. 02:11:908 (2,3) - 02:13:985 (6,7,8,9) - what will you think about this two timestamp. yes they look same (1/4 slider + circle). but look at the timeline. 02:11:908 (2) slider starts from red line, it plays light sound. but 02:13:985 (6) on the white line. this is downbeat, it plays strong sound.
you can see you use similar thing to represent different sound. this is wrong rhythm, it will hurt playing experience.
ok there is a good example, see 02:15:600 (2,3,4,5). this is after 02:13:985 (6,7,8,9) maybe players will have troubles playing this because there is a wrong rhythm.
this might be happened above Hard. be careful when you want to do rhythm change.
how to change them in Normal. 02:11:908 (2) - use a circle. 02:13:985 (6) - can do a 1/4 reverse (but people would still tell you don't make this. use your way to make it easier). about 02:15:600 (2,3,4,5) - don't know what to do for you, you have your way！
(can't put this to timeline tab so move to here)
