Light -> Medium turrets = double damage, more/same efficiency, block sizing unchanged 9 / 9.

Light -> Medium Cannons = double damage, more/same efficiency, 3x the block sizing 8 / 24. ?

Plasma cannons are even worse at 6 blocks for light and 24 for medium 4x sizing.

Is there a 300% tariff on cannons? :p

While I'm on about sizing, basic > standard plasma turbines seems out too, basic is 3 blocks for -200w saving, standard are same or more efficient in everything except size at 16 blocks for -600w saving.
