Shift times will be limited by the actual hardware capabilities in the transmission.
That could be changed by the type of clutches, shift kit installed, band type, line pressures, ect...
On a stock 4l60e, expect values in the .200s to be on the max side of things.
Some people go higher, some people go lower...
As for downshifting sooner, From the looks of that software, you would have to just raise the values a bit in the problem area. As those look like mile per hour for the downshift to occur.. At wide open throttle, it will be using a different table set. They are single perameter values for that event.

yea i realize the closer to zero the quicker the timing is. from .540 i changed it to .525 at the higher 80psi+ range for starters and go from there. small changes
