I think he means in gametime (so, between 70 and 79 turns), as indicated in the brackets.

I don't think any game could last for seven years, since the game was simply not available back in 1998. Other than that, a Proportions game could certainly last for a few years: Proportions #1 is around turn 300, and has been created three years and a half ago. The game is not necessarily a "Last One Standing", so I doubt it will be over anytime soon: I know I am perfectly fine playing the Minbaris.
