In terms of improving performance, there seem to be a number of approaches:
1) Be consistent. Keep shooting at a pace you can make your hits at a 90-100 per cent hit rate, allowing your speed to build only as you continue at that accuracy level.
2) Swing for the fences, as a method of accelerating improvement, recognizing that accuracy may suffer initially, but with the belief that accuracy will follow as you adjust your body mechanics to that new, faster speed.
3) Combine 1 and 2 in a methodical way, that allows for big breakthroughs but in a more disciplined way.
