Spacie Pressure and Grabs

[Toe]

When shielding against spacie nair/dair pressure, and i'm attempting to shield grab, do i grab as soon as the attack hit my shield? Also, I heard there was some marth thread that listed like all different throws and percent conversions so I was wondering if someone could link me to that I'd really appreciate it.

Getting a grab: If they do late aerial - shine - immediate aerial while jumping away, you can't grab them after the attack hit. Your only option would be to hit/grab them before then first aerial while they are flying towards you and don't have any hitboxes out.
If they do throw out the first aerial (too) early you can grab them before the shine comes out, in which case you of course want to grab as soon as you're actionable.

I don't have a link, but this is what @Beat! wrote on the subject:

Upthrow CG flowchart against Fox
Read these notes before reading the flowchart:
- All damage numbers in this guide, unless explicitly stated otherwise, are PRE-THROW percentages.
- This flowchart assumes that you have room to work with. If your opponent starts DIing towards an edge you need to be prepared to cut the combo short with a tipper or dair.
- Every follow-up in every step is reactable. There's no need to guess or read which way they'll DI.
- Pummels aren't mandatory, but they make it easier to execute the following move and the extra damage they tack on means the finishing tipper will be stronger.


1. 0 - 16%: Regular regrabs

2. 17 - 32%:
2a. No DI or slight behind DI: Pivot regrabs
2b. Any other DI: Regular regrabs.

3.0. 33%:
3.0a. No DI: Turnaround uptilt -> regrab
3.0b. Slight behind DI: Uptilt -> regrab
3.0c. Any other DI: Regular regrab -> pummel

3.1. 34% (the reason it's different from 33% is that uptilt starts becoming unreliable against no DI because of its weird "not-upwards" hitboxes. If you actually get the correct hitbox, it'll still connect into a regrab, so if you feel confident that you can get it every time then just follow the chart for 33%):
3.1a. No DI: Rising SHFFL uair --> regrab
3.1b. Slight behind DI: Uptilt --> regrab
3.1c. Any other DI: Regular regrab

3.2. 35 - ~59%:
4a. No DI or slight behind DI: Rising SHFFL uair -> regrab
4b. Any other DI: Regular regrab

5.0. ~60 - ~65%: Pummel at least once before throwing -> delayed SHFFL uair -> regrab (they should now have at least 80%, but less than 90%)

5.1. ~69 - ~75%: Pummel at least once before throwing -> delayed SHFFL uair -> tipper (post-tipper damage should be around 105%)

6.0. ~80 - ~84%: Pummel once or twice before throwing -> delayed SHFFL uair -> tipper (post-tipper damage should be around 110%)

6.1. ~85 - ~87%: Delayed SHFFL uair -> tipper (post-tipper damage should be around 115%)

7. 90+%: Either upthrow -> tipper or upthrow -> weak uair -> tipper


Minor note: The numbers, while accurate, are not TAS-level perfection or anything. There's probably room for small improvements here and there.
