You really think this is the first such study ? <| sep |> The point is to do just that . Why invest points on the Phantom if it ' s not going to be used for much of the game ? Letting upgrades on the Phantom have an effect before it ' s undocked means more people will make that investment . <| sep |> I think maybe mentally you are focussed on the leg and tipping action of UchiMata . Thats ok , but the next level would be too focus more on the entry and hip contact . pulling your opponent upwards and entering below their center of gravity , connecting them to your hip and backside and then following through with the leg as you torsionally rotate your mid section and punch down with your lapel grip . In the progressed style of uchi mata , the leg is just a follow through mechanism . This progressed style may still not be as good for BJJ as it could be since it often ends in an ippon and a roll through , which basically gives your opponent your back . So , try and control your opponent a bit more before you throw , and then you can make sure and control the landing .
