More thoughts because there are lots of interesting variables here. E.g., if the goal is 200 snatches @ 24 kg in 10:00, does one GTG w/ a lighter or heavier weight or 24 kg? We know that occasional work with a heavier bell is good, and also occasional, higher-rep work with a lighter bell, but the bulk of the training should be with the competition weight. This is a change from a strength based approach where the weight used for GTG would almost certainly be lighter.
And if GTG for 24 kg snatches, then what else?
Let's take a hypothetical, but probably quite common, current max - let's say someone can do the 5:00 snatch test and get 100 reps right now. Take 50% of that and do 2:00-3:00 sets of 40 - 60 snatches each throughout the day, starting with 4 sets so that your single day equalled your test volume but spread out.
You'd test periodically, hopefully see an improvement, and revise the GTG sets upwards until, as you approach the final test day, you were doing 4:00 - 6:00 sets of 80 - 120 reps each, and reaching 400 reps per day on average.
I'm just thinking out loud here - I can see how it could work, but the real question is: is the trainee's technique sufficient to allow this volume of training without callus issues or other injury, and is the trainee's recovery ability sufficient to allow this kind of volume day after day and maintain good form?
