I start with a high number high slope (lean with hesitation) and slowly work down until cold take off has no hesitation.
I think the guys who tune the high slope to reflect high load/boost are taking the wrong approach, and hence poor cold starts that tuners try to work around by increasing cold start fueling when cold start tables should not need to be touched. Remember that you are on the high slope on cold starts for most of our injectors.
