1500 Hz   ===>   2x      Δ ~ 17 db
1500 Hz   ===>   3x      Δ ~ 25 db

For a digital mode with a good error correction, this should be enough - 
I think.
With a wider transmission channel (2 or 2.4 kHz) the protection against 
selective fading is also improved.

For the correct display of such tables should be used "fixed width 
fonts" in FLDIGI.
I use COURIER.
I hope this mail program does not change the formatting
