Sports betting injury reports: which books update fastest after news breaks?

Been getting burned trying to play injury news on NBA props lately. Feels like the odds move before the news even goes public sometimes. I hear guys talk about which books lag behind on injury updates and let you grab stale lines for a few minutes, but from what I can tell, it's mostly algorithms reacting within seconds these days. Not really seeing much value unless you're glued to your feed 24/7.

I'm thinking the smaller books might have a longer window, but they limit fast if you hit something that obvious. Trying to build a more consistent approach instead of chasing every lineup alert or hamstring tweak. Wondering if anyone's found a sweet spot - maybe a league or type of bet where there's a little more breathing room before everything gets hammered. Would love to actually use some edge, not just donate to sharper scripts.
