Pielieshenko (UKR) is shown executing a 170k snatch. His time to full extension is .67 seconds and pulling under the weight is .33 seconds, which are typical for most lifters with good reaction times.
Pielieshenko’s clean & jerk with 205k has an overall time from the platform to standing up in 2.2 seconds, this just 5k off his recent best of 210k at the 2016 Olympics where he placed 4th. His time from the platform to locking out the jerk is 5.3 seconds. This particular clean & jerk with 205k is equivalent to a 238k back squat in 1 second or 205k front squat in 1 second. These are the minimum amounts, but in order to achieve the 2.2 seconds overall time there has to be some separation of at least 110%. This will be explained in the description after the next video.
This 280k back squat was achieved in 1.3 seconds in the ascension. 280k - 15k = 265k and 265k is equivalent to 228k clean & jerk. This gives Pielieshenko about 9% more separation between his meet clean & jerk of 210k and the 228k equivalent and this allows him to clean the weight in 2.2 seconds in the overall time. Without this separation, those overall times would be slower than 2.2 seconds and could become slower than 2.5 seconds without any separation. With negative separation the times will degrade even more to as slow as 3 seconds and slower.
This 240k front squat was achieved in 1.1 seconds. 240k - 5k = 235k equivalent in 1 second, and 235k / 210k = 112%. Pielieshenko has a separation of 112% of his clean & jerk of 210k. This percentage is greater than his back squat percentage of separation, and also allows for the faster overall times in motion. The minimum would be a 210k back squat in 1 second, which would not be as conducive to the 2.2 overall time. Separation allows the overall times to stay in tact at the faster than 2.5 second times, which is required for the jerk drive and making the jerk more assured at limit weights.
