*Interestingly, the Lurker seems to have a hidden +50% speed upgrade applied by default. Although its iscript opcodes indicate it should have an average speed of 4, it apparently moves at about 6 pixels/tick.

**The jerky movement of the Broodling is due to its movement being controlled by a random function, and its speed varies anywhere from 5.6 to 6.588.

***Measured in 256 × pixels / tick. Units not listed here accelerate and stop instantly.

Incidentally, it seems that unit speed upgrades has a strange effect on the move <pixels> opcode in IceCC. After the speed upgrade, move 0 actually moves the image by about 1 pixel(?) instead of staying in place.
