Check out www.converter.com and click on "The truth about stall torque ratio"...Its Precision Industries' site...

EXACT OUTPUT TORQUE ÷ EXACT INPUT TORQUE = STR. STR is just what the name implies. The ratio of torque multiplication at stall.

so for an engine do you want more str due to the fact you will launch harder sicne you have more torque?

 

so anyone wanna answer my question?

 

The definition you give is as good as any. But it's not a concept that has much practical use for the end user. If you have a very finely tuned combo and are using a high end converter, you could work with your converter supplier to give you a bit harder or softer hit off the line. Which is another way of saying that you would be altering the STR. But it's not even a term the high end manufacturers use, in my experience.
