Man you folks should do a bit of reading of the history on the board before such weak posts (mostly directed at the OP). The German price has been known for a long time and we have all been using ratios, German, UK, SA, etc. for some time to get a better idea of the US base price. Some ratios seem reasonable, some don't work at all. Then selective choice of data (i.e. totally unscientific and biased) gives you a number you think is reasonable.
The ratio method works sometimes and sometimes not, no real way to predict exactly when it will work.
