Sadly there's not really a point. Even at 15 minutes, the dude who went 0/11/0 always votes no. It's hard enough to ff at 20. People really really hate surrendering in normals for some reason. In ranked, this shouldn't really be a thing either, cuz you shouldn't be giving up that quickly even if it's hopeless. For example, if you're playing as a good team comp with a weak laning phase, and everyone is losing even though mid game hasn't come yet. They start the vote and if you vote no, they're gonna troll and get pissed off or AFK. But you could've won!
The vote should stay at 15. That's when the mid game usually happens and people start grouping. You can usually tell, if you're losing teamfights, that you can't win. But even if every lane is 0/3/0, there isn't a way to tell if you can win until you group. What if they have a Teemo? Or are all 5 AD? And you have a Malphite and Yasuo? With a Kalista bonded to the Malphite? And an Orianna? And a Sona? Like, you're gonna win even if a little behind tbh
Although in theory it sounds good to never give up in ranked - You have to understand that even the pros in Dota 2, during "the international" with millions on the line, would surrender games early even though to the casual observer it didn't look that hopeless.
The reason? It keeps your mind fresher and prevents you from tilting. Plus, as pros, facing pros who don't make mistakes, they had the experience to be a good judge of when it was better to throw in the towel than continue to get pummeled for no reason.
Getting beat up for an hour in a pointless prolonged agony of struggle that you knew was really over from the 15 minute mark is very bad for team morale, is tiring, and reduces the chance that you will do well in the next game against the same opponents. It's not worth doing that to yourself for the 1% chance you'll be able to turn it around and capitalize on a major mistake - especially when this was only the first match in a 3 out of 5 competition.
I've noticed the same thing in ranked play. I'm really far better off if I just wash my hands of a complete crap fest of a game at 15 minutes and start over fresh, rather than tease it out for 30 minutes into a frustrating prolonged stalling of the inevitable. The later leaves you more tilted and more mentally tired for the next round, more likely to lose.
