What is the meaning of ms click?

good evening, what is the meaning of ms click? optimal for razer? someone writes 100,150,200,250. my ping is 44 ms. tell me please

MS is an abbrevation for Milliseconds. While your ping is measured in milliseconds, this use of Ms is completely unrelated. With relation to GSE, It is the gap between button presses. If you have a MS of 250, you are clicking the button 4 times a second.
