> One group did this six times a day for five days a week (6×5). The other group completed all 30 contractions in a single day once a week (30×1)
While this may appear effective for complete noobies, I suspect that the hailed effect will quickly go to 0 when you get even just a little more advanced. To make progress then you can't avoid longer "Time under Tension" sets for your muscles. Which also becomes increasingly impractical to spread 5 times over a day as you first need to properly warm up each time.
