What needs to be done to make Hot Spot 100% correct?We are trying to improve the system. One of the biggest problems we have is when the bat is swung quickly. We get 'motion blur' where the bat is bleary as it is swinging. In those instances, it's difficult to pick up a hot spot. Whereas, if a player is playing a forward defensive shot and the bat doesn't move much, we can pick hot spot in just about all the cases. We are trying to improve that by using different cameras, different techniques. We think we have solved that but the new cameras won't be available for a few more months.
Is it true that if a batsman applies Vaseline on the edge of bat, it could help in an edge not getting detected as a hot spot?That could be possible. Anything you can apply to the bat would reduce the friction (between the bat and the ball) and that can hinder the detection of hot spot. This is not something that we have tested yet, but we will attempt to test it this week.
So, even a tape on the edge of the bat can be a deterrent?That's correct. I saw this last week during the Lord's Test.
There were some stickers or logos or some plastic material on the side of Dravid's and even Ishant's bats. When I looked at that through the infrared camera, it came up like a hot spot.
