Living life in the fast lane
As you can see, it's perfectly safe. In fact I recommend everyone experiment with sub-1250ms times and report back.
While this sounds totally sarcastic to me, using the times in the SUPER GAJILLIONAIRE thread thing you posted, my buy times were pretty much identical to this. What are your buy times actually like? I think I saw in another thread about the topic you posted some buy time of like 2000-3000ms or so which surprised me considering how low the pre-haggle and ocr settings were in the super gajillionaire post.
Or maybe you're not being sarcastic and I'm just dumb.
