To Walk or Not to Walk? That is the Question (Rocheste Transportation)

With the new town of Rocheste, Vindictus players will find themselves traveling to and from Colhen more frequently.  And as such, the people at Nexon implemented a carriage system, in which players may travel from Colhen to Rocheste, and vice versa, for the cost of 2000 gold or a wait time of up to 5 minutes.  For the cheapskates like me, who love to hoard gold, I choose the free options whenever I'm given the opportunity.  So the question boils down to: Do I walk to Rocheste or wait for the carriage to arrive (kind of like your local city Metro)?  It depends.  Walking from Colhen to Rocheste takes about 105 seconds, so if the carriage is scheduled to come in less than 105 seconds, do wait for the carriage.  On the contrary, if the wait time for the carriage exceeds 105 seconds, you are better off waiting.  And if you're both frugal AND lazy (you know who you are :D), you can wait regardless of the carriage schedule and just multitask while waiting.
