No, I'm trying to figure out when I should go with a higher d amount with a minus instead of a lower amount with a plus.

I'd say just go by the Damage Table, B16, and the progression there (which is pretty much the same as +4 equaling an additional die). It goes:

xd
xd+1
xd+2
(x+1)d-1
(x+1)d
...and so on. In other words:

+1 +1
+2 +2
+3 +1d-1
+4 +1d
+5 +1d+1
+6 +1d+2
+7 +2d-1 (although this goes against the +7 being a full 2d under the other rule)

Or combine the two. Any +4 is +1d; any +7 is +2d. For any leftover adds, +1 and +2 are simple adds, and +3 is the next die-1. So, say you had some extreme number of dice+adds like 60d+60; to turn this into mostly dice, you divide the 60 by 7, getting an additional 8x2 = 16 dice. There's 4 left over, which becomes one additional die, so you can roll a total of 78d.

You might want to go to D-scale, round this to 8d in D-scale, or as GM you could certainly just say that the attack pretty much always does its average damage of 270 (60d does average of 210, plus 60) or 273 (78d does average 273), and not bother rolling at all. Or any combination that makes things easier.

A couple of places in High-Tech there are options that increase or decrease damage by (for example) 10%. The only real way to do this is to convert the original weapon damage to averages, apply all modifiers, and then convert back to dice.

I'd think you could roll damage, add 10%, round (down, probably), and apply that damage to the target. But I suppose it'd be a pain to do that every time.

Which is why there's an Adjusting Damage box on p. 166 of High-Tech that, on reading, doesn't appear to omit any corner cases. I'm curious to know what part of that box isn't clear.

Nothing isn't really clear. It just seems that there's no case where a negative adds are needed, so I was curious how I should determine when I need to apply them.

The fraction determines what/when you add +ve or -ve.

Do you have High-Tech? If not, as Vitruvian said, B16 is a good guideline.

e.g. if I created a device doing an average of 47 damage; I'd divide 47 by 3.5 for the number of dice and get 13.42####. So, 13d plus something. 0.42 x 3.5 is 1.47, call it +1: 47 = 13d+1.
Or damage 48; /3.5 = 13.71####. 0.71 x 3.5 is +2.5; that's 1 less than the average for a full die, so 48 = 14d-1.

The box Kromm pointed out, at HT166, makes it easier by listing what a fraction equates to. It also covers damage under 1d and over 12d but B16 is okay if you feel do not need HT.
