I don't understand how those Superlative gas blocks are any different than a leaky traditional gas block, which I have personally seen (more than once) turn a rifle group into a shotgun pattern. The high pressure gas that's exhausted from them could have been used to propel the bullet faster, or at least present a similar volume of gas at a similar pressure to each bullet in a group.
