agreed, this is not HST or even a flavor of it. Haycock's HST had a linear periodization approach, not this mixed rep/set varient each day. Also for HST, you are infact undertraining; minimum gym time is every other day if you are doing a total body split, other wise its everyday varying upper/lower.
On another note, i am often surprised when i hear the original HST is considered 'non-functional' hypertrophy as only the non-contractile elements of the muscle grow. If the plan is followed correctly, training is done in the 5 rep range as well as the 2rep range/eccentric training, both which stimulate hypertrophy in the muscle proteins as well as enhance the CNS's ability to handle heavy loading.
