Visualisation !
When I am shooting well, I have a set routine.
I clear my head of all conversations previous, focus on what I am about to do, visualise the flight of a clay, the required hold, move, lead and trigger point (for sporting or skeet) fit cartridges and align heads, close gun, pause, balance breathing, call and shoot, gun open, remove shells (override ejectors) cartridges in bin, blow smoke clear of barrels, repeat the process until the referee says unload, haven't got a clue how many pairs I have shot, but I do boil at the ones I miss and after leaving the stand I beat myself up mentally and then determine to do better and dismiss the misses, determining to not let any more silly ones slip through the net.
With OT I don't wait for the Flash, I move WITH /TO the flash if that makes sense, but it isn't a rush, or a slash, it's a smooth move, triggering as I move onto the lead edge.
