Who Copies High to Low?
I do for testing or full race tune, to eliminate the blending. For a street tune, I may kick it up a few degrees max but I tend to leave it alone. I personally think its best to account for as many variables as you have time to tune for, and leave in these "safety nets" whenever you can. Knock detection and the subsequent timing adjustment is paramount in making sure you don't accidentally mess something up through detonation 
I do this whenever I mess the timing around, but
I always subtract 4 degrees off the low table
across the board afterward. Just in case I stay
with the tune-in-question and find some bad
gas etc. I try to tune for "KR barely avoided".

I've looked at files from a very well known tuner and also a hand held tuning device and both have the same values in the high and low tables. That's why I am asking.
