Alright testing this reset on the Flash himself and the results are disheartening. the +20 advantage was a rough estimate and belongs to the LKx4 version. With the LKx5 version you get +11 frame advantage (tested with sweep to see if it jails). The weird effect with the advantage however is that f2 (16 frames) plain beats out flying uppercut (6 frames). No trade nothing. I can't make the video until I am entirely positive on the advantages but for now here are the estimates with the current combos being used.
LKx4=+20 (more?), easy to jail with f2 and d1d2 if blocked allows for a little trait advantage leaving you at plus frames to continue pressure, easily confirmable on hit with LK.
LKx5=+10 to 11? frame advantage, gets beat by Flash's backdash (not sure about others, probably Zod). Optimal combo to go for reset when near the corner.
But enough sobbing, a standing reset that leaves you at enough frame advantage to go for a freaking safe 50/50 is not something to forget about. I will make sure to post the video today promise that.
