Ok I'll bite, why would the regulator be set to zero?
My point is the rule is open to not only interpretation, but also becomes a matter of opinion. The rules don't say must or shall be on the high side, but rather says must have one.
We had one that infact did empty the system completely, he just didn't like it on the low side, and seeing as there is no rule that says must be on high side it became his opinion.
How are teams going to be able to figure out what one persons opinion is going to be?
