Channel width for different modes - is this correct ?

Is this frequency table correct ?
Where C is the configured frequency in a Mikrotik - and where e are the additional channels uses
Where the - or + is the offset frequencies space also used in a desired channel configuration?

T = 40 wide turbo -20 +20

C = 20 wide -10 +10

Ce = 40 wide -10 +30
eC = 40 wide -30 +10

Cee = 60 wide -10 +50
eCe = 60 wide -30 +30
eeC = 60 wide -50 +10

Ceee = 80 wide -10 +70
eCee = 80 wide -30 +50
eeCe = 80 wide -50 +30
eeeC = 80 wide -70 +10
