Yeah true, it was soley for context as the percentage quoted yesterday doesn't seem that far away from what we assumed was reasonable fact. It sorta lines up slightly. There is so many numbers being thrown around, 30%, 40%, 50%.
It was more of a question I suppose as while highlighted, were the other 10% was coming from to achieve full 50% power. Its getting a little old now though.
Edit: BenouKat, made a good point, its more than likely just a random assumption (altho I thought better from a relatively recognized dev)
