It's probably fine. It could possibly be a problem when confirming from non-ideal ranges midscreen, like antiair 5P jc j.whatever. I find myself doing 866 in the corner as well.
Instead, you could just worry about optimizing combos whenever you can. I started off just getting used to j.KSD and simple ground starters. Her damage actually increased by like 60 points after optimizing, though.. Leaves them bleeding rather than somewhat low.
