What does the 'gap' in Parallelism (high speed rules) mean?
Another question: I am needing to use the high speed rules for the first time, and am learning what it can do. I am confused on the 'Parallelism' rules however. You can enter a length maximum that...

Re: What does the 'gap' in Parallelism (high speed rules) mean?
Thanks Bill, toggling on the 'aggressor' box did cause it to finally see any violations I was creating. And now I understand the 'gap' value, thanks Randy
