The draw weight on the bow are in 10# increments.For example my Xtec is a 50#-60# model.
The draw length on my bow is 27" - 29 1/2".That is quite a bit of adjustment but not what is listed in the catalog.The catalogs can be misleading.
Now,about the bow.It is a great bow and is really shootable but may be on the expensive side for a beginner.I would reccomend it if price isn't an issue.There are some really good bows that are cheaper,like the Ultramag by Hoyt.This may actually be a better bow for a beginner.It has a brace height of 7 1/8" and an axle to axle of 36".Reflex of only 1/2" so this should be a very shootable bow for only about $360.00,depending on where you buy it ,of course.
Good luck with your choices.
