It seems to me that efficiency of heat and gas go hand in hand with velocity. Wouldn't more efficiency lead to higher velocity? The data show both vents result in the same velocity--hence both vents are equally efficient. This is what the data show. How can one argue against the data? The data indicates both vent design are equally efficient does it not?

The primer on the left were ignited when the domed vent was in place. There is no visible evidence that they saw less pressure than the primer on the right; is there?? Where is the scientific evidence that the domed vent reduces blow back pressure? Where is the evidence? What data shows that the domed vent results in less blow back pressure? To my knowledge--none.
It seems to me that scientific conclusions should be based on data, on data alone.
