I have been busy with real life since getting back from my trip including a pile of paperwork my assistant was so kind to leave stacked on my desk at my office.
I took a break yesterday and had a nice flight into a fishing hole
http://www.simviation.com/cgi-bin/yabb2 ... 1186179268 but that was for fun and not for tweaking.
From what I can tell so far the chart seems to be holding value but each system is different in what number combination may work better. I can not say how well that chart may fair on very slow hardware (ie; 6600GT-7300, x1600 ATi etc) because I have nothing here to test it on. I have one system that likes 70/37 and another that is loving 170/27.
I am behind in things around here because I was gone for 2 months so I need to address the real world before I can dive into the fantasy one. LOL
From what I can see thus far, the scale presented does work but it requires everything be in balance. In example, if your traffic is too high, the scenery sliders are too high, or your autogen is too high (or too low too) you may not see all the the benefits the chart provides or you may not find the most effective combiation on the chart because something else is out of whack.
The sim is very tricky to get pinned down.
