NO! Counting red 2's and red 7's is NOT the same as counting 2's as 0.5 and 7's as 0.5. Let me show you why:
Example: 6D,S17,DAS
A = -1
R2 = 0.5
B2 = 0.5
3 = 1
4 = 1
5 = 1
6 = 1
R7 = 0.5
B7 = 0.5
8 = 0
9 = 0
T = -1
The above tags are known as the RPC system (level 2) which has the following parameters:
BC = 0.9804
IC = 0.7847
Now, what if we count the red 2's and red 7's as +1?
A = -1
R2 = 1
B2 = 0
3 = 1
4 = 1
5 = 1
6 = 1
R7 = 1
B7 = 0
8 = 0
9 = 0
T = -1
Here we have a level 1 system with some poor parameters:
BC = 0.9556
IC = 0.7647
Let's compare the above against Hi-Lo:
BC = 0.9648
IC = 0.7647
As you can see Hi-Lo does perform better.
The same analysis goes with Red 7 counting all 7's as 0.5 and Red 7 counting the red 7's as +1:
A = -1
2 = 1
3 = 1
4 = 1
5 = 1
6 = 1
R7 = 0.5
B7 = 0.5
8 = 0
9 = 0
T = -1
Level 2 system which has the following parameters (in TC mode):
BC = 0.9800
IC = 0.7852
Compared against:
A = -1
2 = 1
3 = 1
4 = 1
5 = 1
6 = 1
R7 = 1
B7 = 0
8 = 0
9 = 0
T = -1
Which is a level 1 system (in TC mode):
BC = 0.9683
IC = 0.7757
In RC mode we should expect lower values.
Hope this helps.
Sincerely,
Cac
