aging a jawbone

After watching an aging the jawbones video on QDMA website (which is a great help), I am still not sure what I would age these two jawbones which I have attached in the following pics. Where the confusion comes in for me is those teeth which have the dentine more than 1x the enamel width but not quite 2x. In the video he states at first that, for the fourth tooth, the dentine must be wider than OR 2x as wide as the enamel on one side of the cusp to get to 3-1/2 years of age and for subsequent teeth its stated it has to be 2x as wide or more (not allowing for wider than but less than 2x as wide). Therefore I'm not sure which it is. In both of these jawbones the 4th tooth dentine is clearly twice as wide as one side of the enamel so they are both at least 3-1/2 yo but the 5th tooth is the question. They look to me questionable as to whether they are 2x as wide or not. Supposing they are not but very close to 2x as wide, how do you age it? I'd also like your thoughts on what age you give them and what your thoughts are on the fifth tooth ie what your rationale is for your age. Thanks and looking forward to the replies.

I'd put them at 3 or 4 but hard to pin down either one without seeing in person.

Anything over 3 1/2 is just an educated guess . Now if you look at jawbones on a regular basis then you will get the age right more often than someone who looks at two jawbones per year .
What gets me is the jawbone of a deer that was born in the swamp . A year and a half old deer from the swamp will have the same dentine as a 4 1/2 year old deer from the highland , just less wear .

So , it is confusing and it's still just a guess but the younger deer are a lot easier to correctly guess their age . Good luck !

c'mon, man

I know there are very few who are qualified with enough experience at aging deer to comment on the questions I've posed. But I also know there a few very qualified folks here who could give a well-based opinion. I am not trying to set a trap and then pounce on anyone's answer with an 'ah-ha, gotcha'. I am truly just trying to determine the age of these deer as accurately as can be done with jawbones, and that is fairly accurate up to about 5.5 or 6.5 years. The ages of these deer will determine what I'll shoot the rest of this year as I can't afford to make many mistakes on the little piece of dirt I have to hunt. If you have a opinion based on a lot of experience and knowledge I would really like to get your input. I also appreciate those who have not commented knowing they shouldn't. Again, looking forward to more educated comments.
