Hmm? Let's see - the average damage from 1 die against an unshielded
is 2/3; vs level-1 shields it is 1/2, vs level-2 shields it is 1/3 and
level-3 shiels it is 1/6.

An unshielded light cruiser (mass 22, 11 dp) takes on average 16.5
to destroy, provided it is not fired upon by other weapons than beams. 
With level-1 shields, it needs 22 dice (ie, 3.7 dp saved by the
with level-2 shields it needs 33 dice (11 dp saved) and with level-3 
shields it needs on average 66 dice to die (ie, 33 dp saved)... IF no 
shields are destroyed by treshold checks. 

The chance for all three shield generators of a level-3 ship to survive
the first treshold check intact is only about 58%, and the probability
that they all survive the second check too is only 17% - which, of
means that the 33 dp saved for the light cruiser in the example above is

rather improbable.

Of course the CL is a rather stupid example since I wouldn't put level-3
screens on it, but still... I think you overrate level-1 screens by 
lots, and level-3 would probably be in the lower part of your interval
in my 

Does someone have time to work out the correct average effect of shields

on a ship which only gets fired upon by beams, taking treshold checks 
into account? I'd like to do it, but it'll have to wait 'til some time 
next year...
