FT: campaign 98 sensor rules, pre-combat

Thanks, John, for the campaign 98 sensors rules.
I like those ranges much better.  I hadn't seen
those and it looks like you didn't include
everything (i.e., ECM/stealth systems and their 
levels, mass, and points).
Are they available somewhere?

Generally, in a campaign, how close did anyone
get before realizing they were outgunned and
"warped" out?  Or is it just as easy to say
"Hmm, you have 5 cruiser and 4 destroyer sized
hulls while I have 1 cruiser and 3 destroyers,
I think I'll leave."? Then everyone can get to the
next strategic turn.  (I've had this problem
in creating and running a Star Fleet Battles
campaign)
