The values you put into 'stats' are taken to calculate the result values used by the game. Entering e.g. '2' for DEX does not give you 2 on each level but different values on different (item) levels.

A long time ago, I posted a link to a LibreOffice spreadsheet in the thread A data collection for stats.
This sheet contains a lot of data with input and output values over levels from 1 to 30. (I think I called the level 'Act Part' as the game does too.)

Hope it's still online. (It's actually 'hosted' by our CM Raze and uses his available space.)

The sheet can probably be opened with OpenOffice as well, but I doubt that Excel can open it ... ;-)
