EXCITED_GROUP_BREAKDOWN_CYCLES
Some further context on breakdown. Unlike dismantle, the breakdown ticker doesn't reset itself when a tile is added This is because we cannot expect maps to have small spaces, so we need to even ourselves out often We do this to avoid equalizing a large space in one tick, with some significant amount of say heat diff This way large areas don't suddenly all become cold at once, it acts more like a wave
Because of this and the behavior of share(), the breakdown cycles value can be tweaked directly to effect how fast we want gas to move number of FULL air controller ticks before an excited group breaks down (averages gas contents across turfs)

MINIMUM_HEAT_CAPACITY
I feel the need to document what happens here. Basically this is used catch rounding errors, and make gas go away in small portions. People have raised it to higher levels in the past, do not do this. Consider this number a soft limit If you're making gasmixtures that have unexpected behavior related to this value, you're doing something wrong.
On an unrelated note this may cause a bug that creates negative gas, related to round(). When it has a second arg it will round up. So for instance round(0.5, 1) == 1. I've hardcoded a fix for this into share, by forcing the garbage collect. Any other attempts to fix it just killed atmos. I leave this to a greater man then I The minimum heat capacity of a gas
