from my expierence, if you have a 3/4" full vortex VS. a 3/4" half, the ROF is not as high..
Size of the hole will make a difference however..
ROF will be different between a 3/4" full vortex and a 1/2" full vortex.
And of course ROF will be different between a 3/4" full vortex and a 1/2" half vortex.
There are many different setups, but in theory and in my own personal tests a full vortex should have a higher ROF and more effeicency since it helps the BBs that miss the first time to get back around for a second try... otherwise they miss and then go down adding more time in order for them to get back into the air stream.
and more time you have in that equation the more Air you have going out the barrel without any BBs.

But if you take it down to a quarter like I did, shouldn't there be a net efficiency gain, since the entire block is only the OD of the barrel, and every BB that falls into the air stream is kicked out the barrel, with nowhere else to go? Wouldn't the only limiting factor to ROF be the rate at which BBs are introduced into the air stream? Or am I missing out on the acceleration that is achieved when the BBs miss the barrel and go around the chamber again?

yes like I said above ROF is dependent on the size of hole as well as some other things.
If its only the size of the barrel then the BB doesn't have anywhere to go and the efficiency is increased. What I am saying is if that design above was a 3/4" it would not be as effective as a 3/4" full vortex.

Ok I started my block, it looks like this. Complete N00b to bbmg's... what side does the barrel go on?

Thanks so much, exactly what I was looking for.

1/2 circle just doesn't work for a vortex. Neither does 3/4.
Even if you have 99/100th of a circle, it still isn't a vortex. The BBs need to be able to spin around in the circle without bumping into a wall. You need a full circle for this effect, so that they can roll around without losing their speed.
Partial vortexes don't exist and are clouds with a smooth breech.
A random idea: Would the width of the vortex matter?
And how about a groove on the inside to guide the BBs even better into the barrel.

Well according to how you have defined a vortex, the width of a vortex block does matter, since it must be significantly greater than the BB to allow the BBs to re-circulate after they miss the barrel, which inevitably happens with any design that fits your definition of a "vortex" or a "cloud".
I bet a groove on the inside would increase ROF if you can come up with some design that manages to feed the BBs into the vortex in a straight line... but I'm not sure if you can do that based on your above definition. If the BBs are just fed in from the sides of the block I doubt they would really catch into the groove with all the turbulence.
EDIT: Do we have a high-speed vid of a clear vortex block construction in operation? I know I've seen one of a cloud, but not sure if there's one of a vortex.
Now, if you could feed the BBs into a full vortex block from a port that is parallel with the barrel but on the bottom of the block, it might be possible to put a groove in to the inside of the block for the BBs to travel in... but then that is no longer a "vortex" because the BBs do not re-circulate, they just travel directly from the feed into the air stream then out the barrel, and you might as well cut out the unused 3/4 of the block and call it something different.
