Human Factors; Procedure
I was preparing to depart for a local VFR personal flight alone. Good weather; no substantial crosswind. Pre-flight and checklists complete. Lined up on runway-final checks done. Aligned on center line. Gradually opened throttle and began takeoff roll. Engine sounded fine; fuel flow; MP fine. It did not feel as though the aircraft was accelerating and gaining speed as quickly as usual. I was concerned that I may have been inadvertently still applying slight pressure to toe brakes. Both feet on pedals; right rudder pedal more depressed than Left to compensate for P factor. Tried to barely remove some pressure from both rudder pedals. Within a split second the aircraft veered sharply left; perhaps 30 degrees or more. I was not moving fast enough to fly; but too fast to make it stop straight quickly. I quickly pulled the throttle fully back; saw the edge of runway rapidly approaching. Nose lifted to avoid obstacles; stall horn sounded; perhaps mains came off a bit. Felt plane hit ground wheels first; bounced once; stall horn sounding; then a firm thud to ground-rolled to a gradual stop in high grass between runway and taxiway. No smell of smoke; I felt ok; just shaken. Shut down engine and all electrics quickly; mags off; key removed. Evacuated onto wing and stepped to ground.I think when I tried to release some pressure on pedals; I let off too much from the right rudder pedal. Engine was almost at full throttle. P factor pushed it hard left and toward non-runway surface. I was alert; well rested; comfortable; properly positioned and secured in cockpit. Plane was operating normally-in my experience with it. I believe I let off R rudder pressure too much. Maybe I should have pulled throttle back the instant I thought I wasn't gaining speed quickly enough.
