after reading, i dont think that you didnt have any power in your drive as you say. i think it would be more accurate to say that the power was focused at the proper time of your throwing mechanics.
watch the pros that can throw a mile, when they throw it looks effortless on their average drive, BUT they are still getting 450' distance. at first i was bewildered at how they can throw such a long ways without huge fast gnarly runups. that is until i got a chance to talk with Dave Feldberg a bit one on one. he explained to me where in your throw you should have the explosion of power and where you shouldnt.

the power should only come in at the end of your mechanics, as he says "when your elbow (of throwing arm) passes your shoulder, thats when you explode"

it sounds like you have stumbled onto that body mechanic, thats great! now adjust your runup angle on the teepad and where your plant foot lands and you will start to bomb into the fairways.
