+(when a gate has multiple inputs, unless specified otherwise, the speed applies to all of the inputs)
+
+
+# General
+
+For multiple inputs, dependencies are evaluated by the order they appear on the gate, top to bottom.
+
+
+# Selector
+
+Cycle input is slow. It does not evaluate its dependencies early.
+Other inputs are fast and behave as normal gates.
+
+
+# Microchip
+
+(with one input and no outputs)
+All inputs fast
+
+The activate input is checked before and independently of the regular inputs.
+
+Other inputs are then checked top-to-bottom
+
+Activation before other, older gates? No
+
+With inner microchips and no inputs/outputs -> tag propogration is instant [microchip_activation_0]
+
+
+# Sequencer
+
+(with one input and no outputs)
+All inputs fast
+
+
+# Sackbot trick
+
+Converting analog to digital with a sackbot is instant. It can be done multiple times per frame and occurs during the same phase as logic gates.
+
+A sackbot uses about 1/250th of a thermometer (~4000 units). It has 16 inputs that can be used (~250 thermometer units per analog-to-digital conversion).
+
+The output can be on for two frames instead of the expected one.
+
+
+
+# Physics
+
+Activating a destroyer and a tag on an object in the same frame causes the tag sensor to not activate.
