would it be too much if they added a rule that all players have to use the same templates? that would guarantee fairness
Would that be any better than the current rule (players use the same templates if one of them requests it)? It's certainly more convenient for each player to be able to use their own set of templates so I don't see any reason for the rules to prevent that in games where both players agree.
Hmm, this might explain why I get an odd measurement for my sharp turn.
Straight 1/2/3/4: 40/80/120/160/200mm
Bank 1/2/3, x-axis: 25,40,55mm
Bank 1/2/3 y-axis: 60,95,130mm
So far so good. Pretty regular
Sharp 1/2/3, x-axis: 35, 65, 90mm
Sharp 1/2/3, y-axis: 35, 62, 90mm (?? 62mm?? )
(all measurements made from the center of each edge).
Again what I am trying to say, the templates IN THE GAME'S CORE SET. All cardboard okay! When you compare to another CORE GAME SET (Cardboard) do NOT align prefectly. They are off by 1-2mm.
Per the rules you are allowed to designate one set of templates to be used during a tournament match. If you feel it is an issue just say you will use one set of range templates.
I can see powergamers bringing two copies of every template, one short, one long!
you have a very dim view on society - powergamers are not always cheats
Turbulence would be a good way to think about it… Except there's not really any turbulence in space ;-)
Touche. But who's to say that the "engine" of your ship is always running at its peak efficiency at the speed its suppose to be.

If they have experienced powergaming from Games Workshop players, then I can see this view prevailing. Ard Boyz always created colorful discussions for the shennanigans involved, and the attitudes it garnered. Whether right or wrong, those perceptions are here to stay.
ok,ok,ok. well now that I have read all the comments on this topic I have a comment and will be asking advice. so first of all a 1mm difference really isn't a big deal to me and most of the players I played with in the tourney if one of us measured range and it was even a hair off then we considered the ships in question out of range. so if I measured and was just out my opponent didn't even bother to re measure he just took that his would be out of range also. so I haven't come across too many people being too worried about that...... YET!!! Now! what I would love to get advice about is a person who I play with in Indy who always seems to move pieces by his hand so that he will miss obstacles even just barely. I don't wanna be mean and even I can tend to jostle my ships a bit when moving them (Although I take every possible step to keep this from happening) but when it seems he will fly over or land on an obstacle his hand slips the piece moves and viola! he misses. any advice on how to handle this with out being a D ?
The manual says that to resolve a conflict where two players disagree, one player rolls the defence dice and the other rolls the attack dice, and the one with the most focuses (focii?) wins the argument. I haven't played in any tournaments, but I would think that such a rule should be used often whenever there is ambiguitiy like this.
I'd be inclined to just make it automatic: if a ship passes within 1mm of an obstacle, roll the dice.
Disclaimer: I've only played about 5 games of X-wing so far.

I think that slight variances will not matter much human error, models sliding slightly etc will all be far more prevalent. Also some times a 5 straight being 1mm longer will be an advantage, other times it will be a disadvantage (like when your doing a K-maneuver to avoid going of the board). As long as your consistent and don't use different templates when it's advantageous.
People who are a pain will always be a pain.
I remember when people worked out the GW dices would roll a 1 in a different ratio to sharp cornered casino dice. And they would have 1 set for leadership tests and one for everything else.
