An unsung benefit of this form of rack pull (provided the bar is set low enough to provide some carryover) is the fact that it's a good way to train the separation phase (the part of the deadlift where you transition from pushing the floor away to pulling with your back) of the traditional form of the lift.
For Eg:- If a GDG is defined with a limit of 30 and 31st generation is created then all the first generation will be deleted and the 31st generation will be created. So at the end there will be generations from 2nd to 31st. Scratch:-This option will delete the generation completely if the dataset is deleted.
