Marth throw followups against Jigglypuff

[FrankDaTank]

Does anyone know how Kadano is able to get wavedash down and forward smash against Jigglypuff when she DIs down and away from your forward throw? According to him it's possible but I can't seem to get it, she flies too far away for the tipper to connect. Am I not acting quickly enough out of the forward throw? Am I not getting max wavedash length? I can't seem to figure it out.

"Dsmash is only recommended if you read their down-away DI.
In any case, all angles they can escape wavedash fsmash entirely, you can JC upsmash them. You have to bet on one of three chances: 1. that she will choose an angle between 130° and 160°, 2. that she will go for 287°-343° and 3. that she will go for a cardinal direction or up-away / down-towards. All of your punishes are not without risk—if you guess wrong, she can punish with rest in time. " From his guide, so based on that go for Dsmash and it should work instead of Fsmash
