I was throwing in a field yesterday working on some backhand shots. When I have the time, I like to work short to long, starting with some standstill drives. Then I throw full-power from a standstill, and then I go to the x-step.
I had a pretty stiff headwind, but I found I was able to put Leopards and Teebirds ~320 ft from a standstill. I managed a couple Valks out to about 370. The crazy thing is -- I couldn't duplicate that distance with the X-step, not even with the high-speed, wide-rimmed drivers. The D was pretty consistent until I started x-stepping.
FWIW, Normal D for me is mid to high 300s with fairway drivers, high 300s to low 400s with Valks/Destroyers/other wide-rimmed drivers, Low 400s with a Nuke, and personal best is ~460 with a Crank. These distances suggest that I'm not getting much benefit in terms of distance from a runup/x-step.
Any thoughts as to why? Is it a product of the wind? Inconsistencies that creep in as I add complexity to the throw?
I should repeat this process on a calmer day, but I suspect this might indicate some attention is needed when it comes to footwork.
