Mudd,
I made the conversion from Rh to LH in 1995 after 28 years RH. I was using a compound then. I started at 10 yards.
To teach myself to shoot a recurve again, I started at 7 yards. When I began damaging arrows (tight groups) I moved to 14 yards. Now I'm shooting at 20 yards. I'm not there yet (damaging arrows) at 20+ yards.
I tried to save some time yesterday and skip 20 and went to 30 yards. Very disheartening! My eye must wander much more at 30 yards -- I moved back to 20.
One tip I'd recommend. Always try to be positive with yourself. Think about what you will do correctly next shot rather than what you did wrong this shot. Feeling bad about a shot is unproductive to say the least! If for example you failed to follow-through with a shot and the arrow hits low, instead of thinking or saying "I didn't follow-through, think next shot I will follow-through." The mind is a funny thing.
