      I’m curious about the PAC conference meet results. They are apparently using the electronic relay takeoff equipment. Whether or not they are enforcing the rule is my question.

      The rule states:

      NCAA Rule 4, Section 14, Article 6, item c (page 56)

      c. If the electronic relay takeoff equipment detects an exchange differential
      (takeoff pad time minus finish pad time) of –0.09 through +0.09 second
      inclusive from the manufacturer’s starting point, the decision(s) of
      the human judge(s) shall not be considered. The determination of the
      electronic relay takeoff equipment shall be official, with exchange
      differential of –0.09 through –0.01 second from the manufacturer’s
      starting point indicating a rules violation and values of 0.00 through
      +0.09 second indicating a legitimate relay exchange

      Now, here are two relay results from the men’s 200 freestyle relay…

      A – Final
      1 Grove City College ‘A’ 1:29.63 1:23.67B 40
      1) Whitbeck, Tim SO 2) Young, Mitch SO r:0.11
      3) Snyder, Drew SO r:0.10 4) Larsen, Peter SO r:-0.01
      r:+0.64 20.65 41.63 (20.98 ) 1:02.81 (21.18 ) 1:23.67 (20.86)

      4 Penn State Behrend ‘A’ 1:33.21 1:30.77 30
      1) Hall, Jason JR 2) Bobsein, Jason FR r:0.37
      3) Porter, Tim FR r:-0.04 4) Spoto, Anthony JR r:0.20
      r:+0.74 22.93 46.08 (23.15) 1:08.77 (22.69) 1:30.77 (22.00)

      Under the rules of the electronic relay takeoff equipment, these two teams should have been disqualified, Grove City for the 4th leg and Penn State for the 3rd leg.

      So is PAC just experimenting with this new equipment because NCAAs will have it? Or are they just looking the other way? I know that NESCAC purchased a set of their own this year, and it will be in use at our championships.

      Any ideas or knowledge that I’m not aware of?

      If one of the pads doesn’t work, then all of the reaction times are thrown out and it’s all on the judges to see it. As far as our relay, one judge called it and the other didn’t think we jumped so we weren’t DQed. The only pad that didn’t work was Westminster’s in lane 4… if you look at their reaction times you’ll see +0.0 for all of them. We have had our system tested but they still can’t seem to figure out why they quit working every once in awhile.

      Interesting. Thanks.

      i also believe that if the ref AND the pad have to call a jump. If the ref doesnt see it and the pad calls it or vise versa, its still not enough..

      Just one other thing worth noting… there’s a girl here at the PAC championships from Misericordia whose start reaction time in both the 50 and 200 have been under +0.20:

      Kocon, Abby FR Misericordia 25.11
      r:+0.18
      Kocon, Abby FR Misericordia 2:02.59
      r:+0.16

      Apparently there’s something about the way she shifts her weight on the block at the start that causes the pad to think she’s off it when she actually isn’t. Can make you wonder about the accuracy of the system, because in finals of the 50 she was over +0.60. (And I’m pretty sure those times up there are physically impossible…)

      According to NCAA rules, the takeoff pads act as one judge. To be DQ’d on a relay you need dual confirmation. So this means that if a relay start is listed as r+0.05 and one or both judges call a jump, they’re overruled. If the start is listed as r-0.05 the relay is DQ’d automatically, regardless of the officials. A relay start listed as r+1.1 with 2 judges calling a DQ, is also DQ’d. The same start with one judge calling a DQ is safe. A relay start listed as r-1.1 with no judges calling it, is safe, and the same start with one official calling it is also safe.

      I hope this was clear, it’s a little hard to type it out. Basically any start time measured between -0.09 and +0.09 is determine to be accurate based on technology used and tested with the takeoff pads. If a pad registers outside of this range, it is possible that the pad malfunctioned, got stuck, had a towel on it, etc… and so these values are rejected. The pad only counts as an official if it registers in the range from -0.09 to +0.09, otherwise it’s up to both officials to dual confirm a jump.
