In this particular case (refinement of TLS + ADP individual) wxu_scale 
is adjusted to the "best" that we found. In this case you are not 
provided an option to play with this value. This is the best we have 
right now. Although this is the most optimized way of doing this among 
existing programs, this will be improved in future.
