I don't know, but I always assumed that's what the oil (and somewhat beer) is for? You put a decent amount in, so by the time you take it out the next day, it's all solidified and slimy. I thought that helped keep the juices in, and poking it was to tenderize it.
^^ A good quality piece of meat shouldn't need holes poked in it to be tender, and you can make cheaper cuts tender by salting them and letting them rest. Then rinse off the excess salt...

But hey, there's a million ways to cook a steak, and everyone thinks they know the best way as this thread demonstrates. There are so many myths about grilling meat perpetuated here that it's kind of funny, but even the experts can't agree. It's easy to find one camp that says room temperature, while the another says it doesn't matter. Some might say salt (and pepper) early and let the meat rest, others say salt right before grilling, and yet others say to add the salt at the end (because seasonings might actually burn, imparting bitter flavors). Some might say it's OK to use a BBQ fork, while others make it sound like your steak is going to bleed out every last drop of moisture at the slightest prick. And the other point that stood out for me is the only turn once rule, vs some people that say turn as much as you like, as often as you like, the more the better.
And LoL at people criticizing Ramsay, one of the most decorated Michelin star holders in the world, like they know how to cook a steak in a frying pan better than he does. A little smoke coming off your vegetable oil isn't going to ruin your steak or kill you, and as soon as that steak hits that pan it's going to suck a ton of heat out of that oil and it's not going to be smoking anymore.
If you want to pick up some decent books on BBQ, check out anything by Adam Perry Lang. The guy is a BBQ guru and has tons of great ideas. I've got this one...

Going to buy a smoker one of these days and a better charcoal grill. I just have a Weber kettle at the moment and some cheap piece of shit gas grill that someone gave us. However, you can take a cheap kettle and add a proper cast iron grate to improve it...
22.5" Cast Iron Grate
This is the one I really want

BBQ and smoking is an art that you can work on mastering for a lifetime. I don't profess to be an expert and am constantly trying to learn new things about it. Basically, at the end of the day, do what
you think tastes good and keep working on perfecting that.
