not having totaled everything up, possibly. this guide is rather outdated in that there are now skill extensions... i.e. concentration goes to i believe lvl 14, DB goes to lvl 10, etc, etc... this was written before those were put into place. As a baseline this will work okay but my recommendation would be to swing by the LC wiki or another place that has the sp cost for skills totaled up and start doing the math for yourself. killing white and green mobs will still net you quite a bit of sp.
