Asian corner handicap?

I keep seeing this Asian corner handicap bet pop up when I’m looking at soccer lines, and honestly, I’ve got no idea if it’s worth paying attention to. I stick to roulette and blackjack most times, but soccer props are everywhere and I guess I’m getting curious. From what I can tell, it’s like a way to level out corner kicks between teams, but some of the numbers and the half-point stuff trips me up. Seems like it would take a lot of stat tracking to find any real edge.

For anyone who's actually tried betting corners this way, is it something you keep in a regular rotation or just for special games? I’m more long-term minded so looking for stuff that isn’t just a random swing.
