Disc fifty - the above posted by Sidewinder is about ideal positioning of the hand using your numbers to put this into clock terminology with 12 pointed at the target and 6 directly away from the target. You start around 8/9ish, as the hand moves past the body it bunches up slightly and gets to about 7 (this is the idea of allowing the wrist to be fluid - not limp but fluid, allowing it to go where it wants to go but controlling it, this will be cocked slightly, but importantly you didn't cock it, the forward momentum did - and yes some players like Avery do keep it a lot straighter, but you need a lot of strength and timing to make this work, I personally have more success with the way Sidewinder describes)
As you get to the furthest possible point with the lower arm chop your focus should be on pulling (and this for me is the main thing to focus on, you are actively pulling this around not letting it happen passively) the back end of the disc round to the front - this is the Hit, this is exactly what Sidewinder describes with his hand position again ending at -4 -5 which on a clock would be 3 or 4 oclock, this final hand position is likely to show someone full hitting it which I assume looking at Sidewinders profile pic he is, if you can hold onto the thing through to about 1 you will be getting a good rip and be seeing a totally different flight path on the disc to what you are probably used to, much more spin for a start.
Keeping hold of it through to 3 or 4oclock and actually making that extra add to the power of the throw (this is where the idea of the reverse thumb lead and the disc feeling like it is being ejected/pushed out of the hand rather than ripping off the fingers -symptomatic of a slip- comes in.) is where you get big distance for minimal effort (apart from seriously worked out lower arm muscles that might not have been worked in that way since your teenage years alone
)
Try this motion really small - further forward than from the right pec. Put your arm out in a position as though it is at the end of the lower arm chop (your point of contact where you would want the Hit to happen) and get your hand so it is at about 8 oclock on the disc - it will be bunched up slightly into your wrist, the thumb should be pointing at about 5 oclock- and then focus on pulling the back end around to the front, now your thumb should be pointing at about 12.
Now add about 6 to 8 inches of just arm movement to this and try to do the same movement timing it to pull the nose of the disc round when you feel the weight of the disc. You will find this is very similar to the hammer pound drills and you may want to do this outdoors as there is every chance it will break your grip if timed right. A very small motion can produce one hell of a lot of energy as you pivot it around your grip. You should also find that to keep your hand on the outside to this point and to keep your thumb pointing to 5/6 oclock you will need to keep your front shoulder closed (another benefit)
