20%? (sorry)

100/80=1.25 or 25% less. . If BD's approach achieves 80% of hypothetical non shared approach then we would have : ie. 200pts in some benchmark for hypothetical design; 80% of 200 is 160pts. Now hypothetical design is 200/160=1.25x or 25% faster.

No offense, but... what?

200 is 25% faster than 160, sure. 160 is only 20% slower than 200, though. The numbers change depending on which number (the bigger or the smaller) you base the comparison on

Edit: Simply put, the "faster than" or "slower than" establishes that the second number is always the one used as a base amount, so you can't make the calculation the other way
