Comptest in MeGUI

if this is my avs script, can any1 tell me how to do a comptest in megui: Code:

megui doesn't do compressibility tests by itself, you can do it yourself by adding selectrangeevery(600,12) to the end of your script and estimating from that. There was an old thread in the AVC forum with lots of empirical research by.. I forget.. which has related information.

i have a prototype code for the compression test. it was made for the one-click encoder but im not sure how to implement it for auto-encoding or the manual method. the "go" button should be grayed and enabled only when a codec and an avs profile are selected... i know i should redesign the form...
