What variable to adjust to make the strip light up faster or slower?

[sparker0]

Hello. We are installing this in our stairwell, and some of our family members walk faster than the lights turn on.
What variable can I adjust to speed up the lighting up of the strip?
Thank you so much! VERY COOL PROJECT!

Each effect animation refreshes in different stages and at different rates. Here are some variables you can try changing for the "stage_grow" part of the loops.

Line 225: effectInterval=5; // make "5" smaller OR
Line 247: gBright = qadd8(gBright, 4); // make "4" bigger

Line 394: effectInterval = 27; // make "27" smaller OR
Line 397: if ( i <= 10 ){ // make "10" smaller
