 now that we have defined some vocabulary, lets actually get to calculating the time it will take to send messages across IPoMC
 
+firstly, if you just want a quick and dirty calculation u can just use this one
+HOPS(HOPTIME) + 2(STLT) 
+you can get stlt quick and dirty by sending yourself a message and timing where that amount of time is T
+STLT = (T - HOPS(HOPTIME)) / 2
+
 The equation to do so is as follows 
 (hoptime is the amount of time that a hop takes in whatever unit you are using)
-(HOPS(HOPTIME) + STLT + (RTLT₁ + RTLT₂ + RTLT₃ ...))
+HOPS(HOPTIME) + STLT + (RTLT₁ + RTLT₂ + RTLT₃ ...)
 
 there can be multiple Recieve TLT's in the equation as there can be track between multiple network nodes in the system
