------- Additional comments from [EMAIL PROTECTED] Thu Nov 8 10:45:05 +0000 2007 ------- I just made a short test, to prove my solutions in a mathematic corse.

This difference is big when I only use a few data.... --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
