The much I remember, what you call "triangulation" was called "master contact".
I would rather use the word "triangulation" in a 2 vs 1 situation where the bearings of the hunters are shared to narrow down the exact opponent's position...
That said, TMA has in my opinion rightfully the status of "art of TMA", even more than the "art of evasion" (the last one is an art to me only I think).
I once was good at it, but it is so complex and involves so many decisions that you need constant practicing to keep effective in manual TMA. In a contacts rich environment where your classification quality is poor, this is nearly a job for a professionals (to me).
I dont know if you play online or vs AI, but what I can say is that well done TMA goes far behind than the simple determination of the contact's position... rather it allows to feel the pulse of your prey, and in some games I had the impression I could read my opponent's mind... yes really
On the other hand, even here, you'll probably not be able to advance much without a good teacher, as it is plainly too difficult to figure all thing out by yourself (except you have a background already). Best would be a teacher "on the field", practical exercises...
On a final note, i SUSPECT 688 i H/K, SC, DW, and the tons of mods, every single installation will behave differently in nearly everything needing a study by itself (that's what finally pissed me off
)
