I see. In other words, it is better just leave it alone and do something else. Because GPU implementation might not pay off due to bouncing textures, CPU implementation might not pay off due to nnedi being much better choice.
BTW that discussion you link to is TL;DR but I think it does not includes anti-ringing which is something madshi made on his own. Also I remember madshi was saying something that he tried to implement sigmoidal algorithm but didn't liked it, so his Jinc might be something a bit different.
