I believe the reason the TO got called over on the sloppy template guy after a few games at the top table was because there ended up being a close asteroid that he conveniently missed because of his shenanigans. I had my own games to pay attention to and I believe I also left after the second round or so because I can't do 4 rounds that start at 7pm when I have work the next morning and player count that Friday pushed it from 3 rounds to 4.
If I would have said something, he would have been caught earlier. It didn't matter in my games, but very good chance it mattered in the games after.
Sometimes I fly Dark Side. I played a 3 round Escalation tournament that topped out at 120 and I ended up with 4 Transdoshan Slavers against a wad of Soontir, TIE/FO's, and AC Tempests. I had initiative so after my PS 2's fired my opponent took his ships off the board without firing with them. Assuming he just forgot to fire I kept my mouth shut. After the game I told him about it and he told me he didn't know that and I felt a little bad. He also forgot to fire with his non-simultaneous fire PS 2's after I fired with mine and after giving him ample time to remember, I asked if he was good for dials and he agreed.
Other times my opponent fires with his ACD Phantom and forgets to cloak, fires with another ship, and then remembers to cloak and puts his cloak token down and I squelch my WAAC mode because I'm kind of a doormat of a person and regret it later because I could have used it to win.
He would have been caught? So you confirmed he was cheating intentionally? Sounds like the top table handled it properly and you did not. Sadly, it doesnt seem like you are interested in helping players, but punishing them. 'Assume the worst' and 'punish harshly any transgression' has got to be a crappy way to go through life.
