Hey all,

In the last few years I have conjoured up quite a databass of measured parameters through the WT3 that I figured I would post in case someone wanted "third party data" for any of the drivers that may have passed by my desk. If anyone would like to include any that are not listed, please post the parameters and I will update it when necessary. There is no specific order.
