It would also depend if it was continuous ICS or intermittent. If it were intermittent, there would be little, if any change, to the strike in distance bearing PJW's point about letency in mind (processors always take longer than relays!). With continuous, you could potentially argue a variable strike-in based upon the trains' braking performance which would decrease the strike in time which obbviously has an impact on distance. A presumption is that strike-in could be as little as braking distance plus a safety margin at line speed. That should obviously not increase the BD as it [the strike in] should already be at braking distance plus margin of the worst performing train!
There is an arguement that train bourne signalling with geographic data plus redundant balises are not quite as laggy as CBIs of old but I have no figures to support that assertion.
