At the start of the burning season I was 4 years ahead and now I'm getting down to 3 years (9-10 cords). I think 3 years is more than enough for me, I just don't have enough room for much more. I can keep 2 years worth in my woodshed and I have a small out of sight wood processing area where I can keep another year or so and get it ready to refill the shed as I go. I'm just about done splitting, been picking at it all winter little by little, good exercise during the lazy winter months. I will be burning 95% Oak for the next 3 years.
