I have developed a nice simulator in which the effects of cross wind and shooter accuracy on a match (i.e. a NRA 6 distance full prone course, or the Dutch 300,400,500m match) is calculated. Under Excel 2010 it runs nicely, however the VBA code has a few bugs under Excel 2003 which I have to fix and for which I have no time. Have a preview at its graphical output.
the brewing is done, creating the possibility to test it with 32bit office 2007 is delaying the release. Tests with Excel 2003 and Excel 2010 (64bit) have been completed ...
