Mod settings, depending on how you want to look at it, either Martin has the incorrect DL specs listed and these are right on the money or they have the correct DL specs listed and the bow draws a 1/2" long. With the cable on the standard post and the mod set on the longest setting which is #5, the bow drew to an exact 31" AMO, on the #1 mod setting the bow drew to an exact 27" AMO. Either way, the bow set up on the standard post will draw from 27-31" in 1/2" increments and will be dead on AMO for each setting, using the draw stop you can fine tune the DL up a good bit or down just a little. Any way you look at it, the average sized archer will be able to get his exact DL dialed in. Because of time constraints, I didn't take the time to move the cable to the other 2 available posts, you can look back at the Pantera specs and get a pretty good idea where this bow will go to using the other posts.
