People who argue against the Twitch rating punishing you for having a fast 10 yard split are honestly kind of missing the point.
Your time at the combine in the short shuttle drill is based on two characteristics: How quickly you accelerate and how quickly you change direction. If you want to figure out how quickly someone changes direction, there's no test for that since you can always reduce your time in the shuttle by being fast.
So to try to figure out how well guys change direction, in a short area, the twitch score came about (and it's really just short shuttle minus 10-yard split). Which is to say we're trying to separate COD ability from just short speed when looking at the shuttle drill.
If two people are equally fast (same 10-yard split), and one changes direction better than the other (better short shuttle) the one who changes direction will have a better twitch score. That's what the metric is for.
Mingo's 10 yard split, compared to his short shuttle suggests that while he is really quite fast, he does not change direction particularly well. After all, guys with worse 10 yard splits (e.g. David Bass with a 1.67, Sio Moore with a 1.62) than Mingo's 1.55 ran better shuttles (Bass's 4.33, Moore's 4.31) than Mingo's 4.39. Ansah was slower over 10 yards (1.56 seconds) but faster in the shuttle (4.26). Mingo's not being punished for his good 10, he's being punished for his poor shuttle relative to how fast he is.
