Fine, define option select however you like but don't complain when other people get confused because you're using it completely differently than them.
What you're describing is closer to a hit-confirm then it is to an option select. Pushblock-confirm, if you'd like.
Its an option select, i dont understand whats so hard to understand.
You DO understand that there are more kinds of option selects other than wiff option selects dont you?
There are meter option selects, wiff option selects, crouch tech option selects etc etc.
Using the term option select here to refer to the game selecting to push your opponent out or not, perfectly conforms to what an option select is.
Using it in a reactable way after the fact doesnt stop it from being an os any more than using a post tech confirm on a successful throw tech, or a cr.lk os tech confirm into bnb damage changes the fact that your first cr.lk was an os tech.
Its just layers of tech being added onto each other. It is simple in concept to understand and apply and only the most rote people out there would disagree. And they would be wrong since wiff option selects were only highly popularized/known about via sf4 and that option selects were known and used waaay before that to describe things that are not wiff option selects.
Case in point chun sitting on 95% meter in 3s. If she wiffs or gets her next cr.mk blocked she wont have enough meter to cancel into super, but since more meter is made on hit than on wiff, if she HITS with her cr.mk then she CAN cancel into super. This is a meter option select, and a famous OLD one at that. One input gives you 2 different things very clearly... Either nothing on block/wiff, or a hitconfirm into super on hit.
And there are LOTS more. 3s is ridden with option selects all over the place, many of which do not conform to sf4 wiff style option selects such as the chun one i described, as well as crouchteching.
Trying to call the pushblock os that i just described, as some new new shit could actually be looked at as a compliment... But no man, its just a simple os. A powerful one that more people need to use if they arent already using it purposefully.
Good day.
