Too lazy to look it up but I know Coach Pendlay and Dr. Micheal Hartman have a protocol for lifters to do snatch and clean and jerk 'OTM' (on the minute). I believe if you look up Doc Hartman's blog he is actually doing this now that he is back into lifting. This would be singles. So you get the volume effect and the ability to concentrate on setup and execution of singles, which, after all, is how the sport is contested.
As well, Charles Staley, of EDT (Escalating Density Training), had an article on using EDT for the classic lifts.
In both cases I believe they were most likely using 80-85%.
Not GVT (isnt' that 10x10), but different approaches that can be utilized at different points down the road to bigger lifts I suspect. OTM may be a better approach to increase volume and workload. I agree that high reps on the technical lifts can be counter productive.
