I think you guys are overreacting a bit much. There is no magic number as to how many times you should check the plugs after each pass. That's why you have UpRev. Monitor your conditions on each pass.
Do you know how long it takes to access the plugs? You have to remove the brace, intake manifold and the throttle bodies if I remember correctly. It was not a quick job that's all I can say. Doing that at the strip will take forever.
This is why I don't usually post because there are a lot of different opinions, or people who no first hand experience, or people who just recently sprayed and have gotten a false sense of security.
Read other forums besides here. Read all the knowledge. Buy all the safety precautions. Learn how to use them, know what they do, know the ranges each readings should be at.
Remember every car has the same risks when going F/I, the key is knowing the limits and knowing the ranges things need to be at. I've ran through more than 30 bottle refills and several passes down the drag strip with no issues for 3 years, take it for what it's worth. GL guys I'm out.
