Tourniquet Time

I hope someone can clarify the following scenario for me:

A surgeon was performing an arthroscopic acl reconstruction and deflated the tourniquet while preparing the graft. When it was time to re-inflate the surgical tech asked if I cleared the tourniquet prior to re-inflating. My response was no. I explained that I document the times that the tourniquet is deflated and inflated during the procedure but the machine isn't cleared until after the procedure. The tech went on to argue that it should be cleared each time it is deflated so the surgeon's tourniquet time will be accurate. I didn't clear the machine and continued with my circulating duties. At the end when the surgeon requested the total tourniquet time I answered by what the machine read. The tech subtracted the first time of 40 minutes from what the machine read and said that was the correct tourniquet time. Who was correct in this situation??

Thanks!
