I'm a subscriber and think the draw odds are correct - but truthfully have never dug too deep. You can of course get the same information free if you do your own research with state websites. Worth it is really up to you. I find it convenient, easy to use and I like to compare units quickly so for $25 it's worth it to me.
I've been a subscriber for several years and have never felt cheated. It's especially useful when comparing several units and jumping from state to state. I've caught a few errors but typically pretty minor or at least obvious.
Money well spent! All the state information, website links, trophy quality and public ground scores for almost all units. You can also save a hunt portfolio with all your points for each species in each state and save your favorites units.
I use it as a resource, but you have to go into it with your eyes open. Certain states don't provide enough information to develop fully accurate statistics. That is particularly true with Arizona (non-resident) and Nevada.
