ok colin, some first questions and notes after being tired of watching your break
0/ funny u always do the same. u aim first at a normal stroke position. u then move your head and body higher to get the arm straighter (waightlifting thing), u do 4 new adressing strokes and then u fire. cool prebreak routine. ps you showed 2 ways to shoot. one where u bend your shoulders and get power from there, and the other where you body moves upwards. it seems the shoulder turning would be a movement that would help consistency and control more then the upwards movement. could u explain me the differences in the 2 moves? why did u chose for the one option?
1/ u are right, your body moves forward and upwards, at the exact moment that your arm (that was at a 125° with the cue, because u are gripping it more forward) is exactly 90°, thats when u start your body movement.
first your back leg thats is slighty non straight, straightens a bit and moves your body forward, this bends your forward leg even more.
2/ the time your body starts to move forward because of the back leg pushing forward. thats the time it takes for your stroke to go from vertical-arm position to fully behind and ready to fire.
3/ at the exact same time, u then completly stretch the forward leg that was highly bend due to the forward movement, giving u a vertical movement, while the leg behind straightens up at the exact same time and gives you the forward movement. combining into your forward and vertical movement.
4/ this forward and uppermovement , is in the opposite direction of the arm and grip moving backwards. these combined give this (coin flipping) movement where the backwards movement is the movement that (blocks) you forward movement.
5/ as your body then jumps upwards and forward, your body Pushes your arm
then forward, giving the coin flip arm/shoulder movement. (blue line) and if at the same time u do the same with your wrist, (smaller blue line) you have the snap break movement.
6/ u finally end with a almost perfect straight back/body letting the cue folow true in the air because your body movement was vertikal, your folow will go the same way. upwards and forwards, straight to god
7/ u now have the perfect godly break
ill try to post a VERY slow motion on youtube or my website for those who want. but its hard with a break that only consists off 6 frames.. but im sure with flash i could do quickly something. ill do it now, and post in some minuts.
EDIT: for all those who want, u can download a slowmotion picture that has been worked on a bit, to make it ok'ish in quality. hard to make a 30second video with only 6 pictures, but it looks ok. .

now that i can see the slowmo in bigscreen, its time to train this movement. AFK for some hours

hope u dont mind i worked on your original video colin. but it was to fast and to small for me to compare to what im seeing in the mirror. if u need any more help with slowmo's u let me know.
ps if u ever are going to get a better way to film yourself, look at the Frames Per Second. thats the most important part. video's on youtube arent bigger then 320x240. almost all digital picture cameras have 640x480 option. so if you are only going to post them on youtube and not commercialise them, u can do pritty well with a 320x240 and 30FPS. almost any digital camera can do this. u could do with slower fps, like 15, but if you are going to make slowmotions, the higher the better
