Question about trigger area of effect and cluster trap spread radius

According to the old wiki and the new one: https://www.poewiki.net/wiki/Cluster_Traps_Support

"Cluster radius - Traps thrown with Cluster Trap will always land within 20 units of the targeted enemy or location. Notably, this means with enough % increased Trap Trigger Area of Effect it is possible to increase your traps' trigger radius enough that they will always trigger against a stationary target. For standard sized enemies (radius of 2 units), this is achieved with a trap trigger radius of 18, a total of 224% increased Trap Trigger Area of Effect."

Does anybody know if this info is correct? Where did the wiki editor get this information from? I looked around and didnt find any sources. Im trying to min max my exsang trapper so the traps always trigger when they land on top of a target, instead of being thrown randomly because of chain reaction. Thanks in advance.
