I've seen numerous people say you shouldn't pump above 5Hg, while i've also seen a lot of people say they pump at around 10Hg. Obviously this is a huge difference. I've even seen people quote "no pain no gain" (which i'm pretty sure is bad advice). So, how much Hg do you take it to and for how long? also, feel free to comment on why 5Hg is too little/much or if 10Hg is too little/much.
