Pavel high tension

In an interview with Pavel Tsatsouline he makes this statement
“But if you set it up like this, if you use a heavy weight and do reps of five (not taken to failure) with only one or two minutes of rest for up to twenty sets, you’re going to be able to use a heavy weight and get a great pump. Every bodybuilder who’s tried this approach has reported sensational gains.”

What % of 1RM would be good to use?
Do any of you know of a training programme that incorporates this?
