This is one of those experiment and see what works best.
I strongly suspect it will make no difference at all. You are likely trying to use a setting to correct a problem you do not actually have.
This is generally used in a office type of environment where you have a large number of devices attached to a single wifi source. At times these device can not hear each other transmissions and since wifi is a half duplex medium you will get data collision/interference. This setting to some extent can reduce that.
In a home environment the source of interference is likely outside your house. The interfering signal is not attempting to even communicate with your router it is flowing between the neighbors router and their end...
