Dick, I can't say for sure about that particular run, but I was spotter in second heat and I noticed they ran out to check that cone pretty often, but only called in a cone maybe 30-40% of the time. There was definitely one case where they called in a cone and then retracted the call after they checked it.
I figure whatever the computer shows is kind of like a baseball ref's call. Sure there's room for error (and in some cases discussion may be warranted), but in the interests of getting on with the game we generally just go with it.

Glad to have you back with us, and I'm impressed at how smoothly you have converted your skills to a very different beast.
