whether the thresholds for where the umpire's call element kicks in is correct is another matter. that bairstow lbw earlier would have had leg stump knocked out of the ground but he is saved on the basis of 0.02% of the ball's width”

hard to see the umpire call changing either, since not actually sure it got the result ICC were looking for either in the test they did, was going to post this earlier but wasn't sure it was correct so didn't want to post it but anyway the error of the hawkeye is 1 and half inches which is the size of a golf ball which is very good at determine the height compared to the stumps but very average compared to the width of the stumps, essentially it is only 100 percent guaranteed to be out if it the middle stumps, get tricky when it hits the first or 3rd stump, since the accuracy of the results drop from 75%-50%, suspect the umpire call is big or close to 50 percent of hitting stumps to account for the golf ball size error.
Not sure if the results are correct and the telegraph article was worded weird since it only mentioned the height, hard to see 1 and half inches being correct for width since I suspect with that error for width no one would accept Hawkeye for the DRS.
For the hawkeye to have credibility it probably needs to have an error of 0.75-1 inch error for the width.
if it hits the middle of the third or first stump it need to be close to 80-90% accurate of being out rather than 50-75% it would be if the error was 1.5 inch.
Just so people can see how big 1.5 inch error his, the size of the Stump is 1.5 inch.
