Just answer for yourself - we sorta know the average number of hours people play and frontier absolutely do.
The problem applies both ways - if someone only plays 80 hours in the year but thinks they should finish it in 6 months they'd answer 40 hours and it might appear they want to smash it all out in days after launch. Just vote for how you play and the statistics sort that bit out enough so we can get a distribution of how long after launch people think they should have 'completed' the content
Sure, did not mean to be disrespectful. Frankly, I answered NOW, because in my opinion one month of game time is too much.
Personally, I would expect to gain at least multiple ranks for an engineer for each day of game time, at least 1 rank per hour of play.
