I agree that the document could be better. For example, it doesn&#39;t tell you to negate (multiply by -1) the lesser of the Read/Write Lag - but in their example they did, so I assumed that I had to negate mine. It also doesn&#39;t say what to do if one or both numbers are negative (absolute value???!)
