Strange, when I clicked on "post a response" to Acesfool's message 2 threads down, it sent me back to the threads list.
Anyway, Red7 is actually a veiled attempt to make a level 2 count into a level 1 count. By counting only the red 7's, you're actually counting each 7 as 1/2 the values. The problem comes if you have one color of 7's clumped near the front or the back of the shoe, then your count becomes a little screwy. It's more accurate if you just count all 7's as 1s and just double all the other values. http://www.bjmath.com/main.htm (Archive copy) <--note how close their performance is to each other. It's a tossup, but I would suggest KO if you're not used to count the colored 7's. I've actually heard of a guy who sometimes gets mixed-up because he ignores the black 7's and then forgets to count the red 7's.
