RHETORICAL QUESTIONS:
- Does this mean that LBB2 drives (A, B, C, etc) are actually installed as "pairs" of drives?
An LBB2 (or LBB5) drive is a system that you can draw on the deck plan however you want. You can draw it as 17 tiny thrusters, but they are still a single system and can be destroyed by a single hit. In total they should have about the volume of the lettered drive.
Just like a "stateroom" is 4 Dt living space that you can divide into as many cabins, rooms, and corridors as you like.
S7, p15-16:
ScoutICourier (Type S): Using the type 100 hull, the scout/courier is equipped ... The ship has jump drive A, maneuver drive A, and power plant A, producing a performance of jump-2 and 2-G acceleration. ...
These are a set of three A drives and power plant (S7 p17):
This is a set of two A drives and a power plant (S7 p17):
- If #1 is true, then does there not exists 1/2 of an A drive [according to S7 rather than a "house rule"]?
No, by RAW there are only A, B, C, ..., Z drives. Drives can't combine, two A drives does explicitly not make a B drive, however you draw a deck plan.
What you infer or think is a reasonable extension is a house rule.
- Since LBB5 specifically states that I can use LBB2 drives in a LBB5 design and S7 identifies a 1/2 A drive as something that exists, is it really a "house rule" or a component from a supplement (like Jump Cables from S9) that we need to create our own stats for (like Laser Pistols)?
Both a ½A drive and a Laser Pistol are added by you as you see fit, so are your house rules.
So the nature of the CT BEAST is that the line between "house rule" and "interpolation of official rule" is a deliberately broad a fuzzy line.
Are JUMP TORPEDOES a RAW or a HOUSE RULE?
Depends on the edition you use? They are RAW in LBB2'77, but gone by LBB2'81 or even LBB5'79.
Ultimately, even the "OFFICIAL RULES" appear to have an element of "somebody's house rules" to them ... so labeling EVERYTHING a "house rule" isn't the answer, either.
RAW is someones house rules, e.g. MWM.
MWM (the Super-Referee) makes RAW. We call it RAW because it is printed in an official book, not because it is better than anything else. It's just our common reference.
The Referee makes house rules for his game.
The menial player can only suggest house rules to the Referee.
Ultimately the local Referee makes the rules for his particular game, taking RAW and the players in consideration.
But, of course, you do not set the rules for my game and vice versa.
