My typical 8 point has an extra point off the G2 that actually splits in 2. That is on the left side of the deer, so it is on my right when looking at it face on, My buddy shot a 9 point the other day and the odd point is on the left also.
When a deer has damage to a leg it typically causes abnormality in the rack, in the form of missing points, extra points etc. When the rear legs are affected you typically see rack abnormality on the opposite side antler growth. When the front leg sustains damage, you typically see abnormal growth on the same side I believe. Of course there is no guarantee that this will be the case every time, but from what I have read and observed it seems to be the case most of the time.
Another possible point is blood flow and how deer lay down. If you look at a deer rack, you will often notice that one side of the antler is curled in (or pushed up higher) more towards the center line. This is often the result of which side the deer sleeps on, as the rack while growing is soft and will hit the forest floor and actually be formed over the growing period and have one side actually pushed in. Another thing I noticed is the G1 or brow tines are smaller on the side with the fewer points on both deer.
On my other racks, standard 8 point racks, and each one sports a smaller brow tine on the side that has its main beam pushed in or up, indicating his favorite sleep or resting position.
Is it possible that on some deer the blood flow is just a little restricted due to the time spent on that side? Enough to curb the flow of blood and nutrients to that antler causing it not to develop as many points?
Just speculation on my part, I haven' tread anything that would prove it out, yet anyway!
Bandgod, maybe rephrasing your question and getting participants to look at their mounts and racks, would help figure this thing out.
I would maybe ask if the side that sports fewer points looks like the sleeping side, and if the side with fewer points has a smaller brow tine, again the sleep side will be pushed in towards the nose centerline or pushed up higher than the opposite main beam. Just looking at over all exact measurements as far as total inches might help to figure this thing out.
Very good question by the way! I enjoyed working through it and have thought about the same thing myself before as you can probably tell by my answer.
