What are the optimal V-Beam settings for redness and telangiectasia?

Hi, I've had 3 sub purpuric vbeam treatments so far for the nose. My dr doesn't want to do purpuric because I have brown Indian skin. He has so far used 7mm spot and 6 ms pulse width and has gradually increased the energy (currently at 10.25j). I have definitely seen improvement but there are some stubborn superficial vessels still there. I'm interested to get expert views on the settings my dr has used so far and suggestions on getting rid of the remaining vessels.
