Question about lag and Marth's Nair

[TheFifthMan]

If you simply short-hop fast fall Marth's Nair as opposed to doing a full shffl'd Nair, how many lag frames will there be?

 

[Tyson651]

quite a lot, probably 1/4 to 1/3 of a second on estimation, so that would mean 15-20 frames?

 

[pyrotek7x7]

It should be twice as long as one that is L-canceled.
