33" draws are few and far between but not impossible. I had a guy wanting me to build a bow for him, said he had a 34" draw, being skeptical I asked how he measured his draw length. He said he held and arrow in his hand and simulated drawing it without a bow.
I told him to place the nock in the middle of his chest and extend his arms without stretching and see where the tips of his fingers touched the arrow shaft in front of him, the length was 29". I built him a bow for a 29" draw and it fit him perfectly.
