A question was raised about my kneeling position during the winter league this year, because the foot was flat verticly, I hit both targets, the guys I were shooting it said it was a questionable position but agreed I was taking it to disadvantage myself so gave the targets. I have had this happen numerous times at local and national events. My worry is that if a marshall is on watching the lane how would they interpret it?
I would have no problem with your possition foot vertcal or flat, toes turned under or not,
provided that your foot from heel to toe is in line with your lower leg with the toe of your
foot touching the ground.
