 YARM-ticks-between-checks=When a resource site is being monitored, the amount of resources in it is only updated once every N game ticks (60 ticks = 1 second), based on this value. Increase to hopefully improve UPS, at the cost of needing longer to update a site's estimates.

 YARM-grow-limit=Maximum distance from the original center that a site may grow when it is created. -1 = Unlimited growth. 0 = No growth. More than 0 = Limited growth.
 YARM-adjust-over-percentage-sites=When enabled sites will have their "initial amount" set to match the current amount, if the current amount of resources is more than the one noted initially. Can be used as a temporary fix or a permanent check.
 YARM-nominal-ups=The number of updates per second that YARM will assume when calculating ETD and mining speeds. 60 is the default, but if your game is consistently running below the default, adjust this value to your average UPS to get more accurate estimates and speeds.
+YARM-make-fake-ores=When enabled, YARM will create a phony item for each resource that, when placed, will create a mineable deposit of that resource. The items cannot be obtained. This is necessary for counting the number of ore entities while dragging the selection tool but may interact badly with other mods (e.g., AAI Programmable Structures) and is thus off by default.
