I think adding digits at 3, 6 and 9 is going too far.
The standard Dartmouth dial is busy enough with all the prominent hour and minute markers, but at the same time has a simplicity to it. Adding digits is too much.
Besides, we are again moving away from the ethos of sticking to the base model (as voted on); therefore into the realm of it not being possible or allowed.
Finally, I don't like the idea of using blue, even graduated, on the Dartmouth FLE as it is too close to the standard Series 1 model. Green, red, grey, we've not seen an orange or yellow (although CW have used these recently in the C60 Trident MkII 316L models) are OK; but not blue.
