I play Rose, whose bnb combo is a 1f link (cr.lp, cr.lk, cr.mp xx ex spiral). I can hit it in training mode, but I usually miss it in actual games. I always assumed that was because I sucked and was getting flustered by my opponent or cracking under pressure or whatever. That could still be the case, but playing with the input lag option in the training room was enlightening for me. If I changed the # of frames input lag option, I would start missing my combos, the same way I would online.
Is playing a person online similar to selecting a random value (between 0-3, say, for a good connection) for input lag in the training room?
If so, I’m not surprised anymore that I can’t hit my combos, I’m surprised anyone else can hit theirs! I’ve seen people in videos hitting their combos online, so that means it’s possible to do consistently? Or is that just because 1) they had a really good connection (0 frames lag), or 2) they only upload the videos where they make all their combos. Does anyone have suggestions on how to hit links consistently online?
I had two thoughts:
 Practice recognizing different levels of input lag. In theory, based on ordinary moves someone could recognize how many frames of input lag they were playing with, and adjust their timing accordingly. This would be especially hard if the lag changed during a single match.
 Forget what’s on the screen (in fact learn to block out all light and sound) and get the timing in your fingers, so the level of input lag is irrelevant. This would give the entire combo though 1f tolerance—for instance before there used to be some leeway because cr.lp chains to cr.lk. If you’re not looking at the screen then you only have 1 frame tolerance for the cr.lk. So all combos would get much harder.
Really both of these ways seem too hard for me, is there any other way? If not I think I will just stop trying to use 1f combos online.
BTW I live in the US and have a good (by US standards) connection, about 10-15ms ping.
BTW2 I know people will tell me to play offline, but I also want to play online.
