I feel like so many people are confused on what actually matters and what doesn't for slingshot on shield pressure
Consider:
-Out of shield speed/hitboxes
-Hurtbox shifting
-Jumpsquat = 3 Frames, Dashback shift depends on character
Happy to discuss, this is only slingshot as SHIELD pressure
Gren Nair here would get punished by GnW UpB cuz -3 vs frame 3 OOS
Gren could SHIELD Bayo UpB (Frame 6 OOS) but not dash back from it cuz of the startup/not important shift
Shield grabs are a bad metric tbh LOL
Frame 7 Usmash OOS* means that after 3 frames of Jumpsquat Gren doesn’t have anything to avoid it Frame 1 (If it was frame 6 he couldn’t get airborne), while Dashback gets him away in Frame 4 (3 dash back frames + hurtbox shift)
So this slingshot mixes both and pressures :)
