Ohh - sorry. Well. Have you though bout added resistance? Use 26/28 AWG long LED wires for example?
Sure you can rebuild the ramping table easy enough by running the Python script, tweaked to your needs, and redefine all the mode sets. In the source code I include the full python script options I used to build the tables (several). It's TK's pythons script: level_calc.py, in her repository.
// For FET+1: FET and one 350 mA 7135 (tested/verified to be smooth):
// level_calc.py 2 150 7135 3 0.3 150 FET 1 1 1500
