So...
We have been playing X-Wing for quite some time in our league without issues due to "pre-measuring". The rules were clear, you cannot premeasure before placing your movement dial, but that other things could be measured "before committing". We took that at face value, found premeasuring to be a minor added bonus to using action-moves and was one of the ways high-PS pilots were able to take advantage of their PS.
Since the release of the new FAQ, with the kinda-premeasure-but-not-really, committed-unless-you-aren't tournament rules we have had troubles with premeasuring during target selection for shooting, Navigator/Fett, what precedent is set, etc.
I would respectfully suggest that FFG leave well enough alone, and dump the "new and improved" tournament style totally optional except when they aren't rules. You cannot premeasure when selecting your movement dial, otherwise you can measure away before making decisions. It was much simpler, made for less frustration for new players who are still learning, and didn't call for judgement about when someone was "abusing the rules" and when they weren't. In tournament play you can simply penalize for stalling if the judge feels it is appropriate, and leave well enough alone.
