Any Advice on 16 vs. 10??

I have run several simulations (2billion trials on 6-7-8 Software) and the 16 vs. 10 index comes up 0 some times and 1 some times. I use Hi-Lo count. I know this is a valuable index so I want to get it right. Also, it seems that because of this variation between sims, the difference in EV near 0 is very small.

From this I have decided that no matter what I do near 0 is okay, but the value really comes in at high or low counts. I have decided to hit on any negative running count and stand on any 0 or positive running count.

I am interested to hear any advice on this mundane minutiae. It bothers me much more than it should.
