Yes, it's been around for a long time. The thing is, since the physics has been the same for years now, the wr's set by using the normal methods have been pushed to the absolute limit. So to beat them without using unfair methods is really really hard. But by exploiting this button clutch thing, you can easily beat most wr's with up to 0.3 seconds. I'm counting at least 20 wr's set just last month, that's not using auto clutch, so I would definitely say it's happening more now than before. I guess respect and fair play is not so important in LFS anymore. That's what's so sad.
