Check Speed potential through standing longjump

Three years ago we asked some speed experts how fast they thought the non-speed specialist could do it. As they thought it would take a year of physical training and getting the sequence optimized to go below eight seconds, we now know they were wrong. One reason for them getting dead wrong might be that Sean McColl had been struggling for years without doing any sub eight seconds run. With Yushiyuki Ogata doing 6.71 and also Tomoa Narasaki getting sub seconds without any proper physical training at the same time many struggle getting below ten seconds, it is clear that climbers have different talent. Talking to some coaches and athletes this has also been confirmed. The Norwegian coach Reino Horak says that he thinks standing long jump and sprinting 20 meters are good indications of who can be the fastest. Possibly this means that if you can jump 2.80 cm, without any training, you can go below seven seconds?
