I have a few questions about T-Matrix.

In excel, I am suppose to work with powered matrices to construct a weighted T matrix, using a scalar of .7.

Does this mean I multiply each of the powered matrices by .7? Or do I power the powered matrices by .7? Or am I completely off base?

My notes say T-matrix is calculated by powering the minimal information matrix up to the diameter of the system. So if I'm using the maximum diameter of the matrix (let's say 6) in the t-matrix equation, where does the .7 comes into play?
