Thanks for the clarification. I see the reference on pg 50 (that I hadn't seen before) that says "The number of active screens that a spacecraft can support is limited to the power plant divided by 2, rounded up."
And I also see on page 65 that there is a table relating "the number of screens that may be combined together depending on the Tech Level of the screens", where;
TL - Nuc Dampers - Meson Screen - Black globe
12 - 1 - 1 - 0
13 - 2 - 2 - 0
14 - 4 - 4 - 0
15 - 6 - 6 - 3
However, on pg 64 there is a table above which it states "The power plant rating also determines what weapons and defensive screens of each type in each screen group the ship may carry." This table shows:
P-Plant Rating - # Screens
1 - 1
2 - 2
3 - 3
4 - 4
5 - 5
6 - 6
So I guess the Table on pg 64 is what had me confused. Since I hadn't seen the note on pg 50 I had interpreted the Table on pg 64 to mean that for a Power Plant Rating of 2 you could have a total of two screens.
The example on pg 50 under screens is a bit confusing because it talks about a 20% flicker rate for a single group of two black globes but the accompyaning table appears to indicate that this might actually be 30% (if I am understanding correctly).
Anyway, this example shows that for a ship with a power plant rating of 4, but fitted with 3 nuclear dampers and 2 black globes "Due to the size of the power plant the maximum number of screens in each group is 2" (presumably the power plant rating of 4/2). It then goes on to note that the designer breaks the number of dampers into two groups, where the primary group has two units and the backup group has only one unit. It also notes that the two black globes are grouped into a single group "enabling a flicker rate of 20% to be maintained."
Although I had previously overlooked the info on pg 50 before, when trying to lay out a ship, reading it now it kind of seems that the references on pg 50 and pg 64 kind of seem to contradict each other, unless maybe pg 64 is talking about the total number of each type that a ship may carry, and pg 50 is talking about how many may be active at a given time (or something like that).
Since I'm very new to MGT Rules, I'm not real sure I'm fully understanding this. If anyone can help clarify I'd be very greatful.
Thanks
