Let's just be clear.

Round Robin (r and R) will go through all the channels in order (ascend or 
decend) before reusing a channel.

group (g and G) will find the first available channel (lowest or highest).

So if you are using r, the order is always 1 2 3 4 5 6... and will not use 1 
again until all of the others have been used.

And if you are using g, the order will be the same BUT if a lower-numbered 
channel becomes free again it will be selected instead of the next numeric 
ordered channel.

e.g.
call out: uses 1
call out: uses 2
call out: uses 3
(call on 1 finishes)
call out: uses 1
call out: uses 4
call out: uses 5
(call on 4 finishes)
call out: uses 4
call out: uses 6

as you can see, it always uses the first available channel.  G is the same but 
uses the highest numbered available channel.

If you're trying to avoid glare, use g.  If you're going for "even usage" then 
use r.

And please, for the sake of the list, trim your responses; there is no need to 
include the ENTIRE email you're replying to.
