...when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the state of Science...Lord Kelvin

Testbed

To the left you'll find my test data. Within any test group, the data should be reliable in a comparative sense. My technique and methodology has changed slightly over time, making it a bit harder to compare results between groups. Not that some comparison can't be made, but that subtle differences between groups are less statistically significant than subtle differences within the same test group. What about test individual driver tests? Take them for what they are worth. Still useful, but the data is a bit weaker here. At this point, I am trying to include a well tested driver as a control for every test of a new driver.

The current test bed consists of an Athlon 64 3000 running XP pro with a Delta 410 for emulation and Praxis, 2.48.

The simulation PC is an Athlon X2 4600 with Praxis 2.48, LspCAD 6.33 pro and Soundeasy V14.
