Sykofizx software and interleaved tracking

[Skyler Jennings <sgjennin@xxxxxxxxxx>]

This question is for those of you who are familiar with the TDT  
Sykofizx software.  I am interested in implementing an interleaved  
tracking procedure where each individual track has a unique stepping  
rule, and as such, estimates a specific point on the psychometric  
function.  Does Sykofizx allow you to do this?  I know you can  
interleave conditions, but have not been able to find documentation  
on how to interleave tracks which estimate different percent correct  
values.  I've contacted TDT, but so far they haven't been much help...

I appreciate any insights you may have.

Thanks,

Skyler Jennings
